I have a domain name that I registered with a site called DotEasy. I am building a web app that I am going to host on AWS and I would like to use AWS Route 53 for my DNS. Ideally I'd like to use Route 53 as the registrar as well, but I'm not sure if that's possible and I've also heard it can take ~3 months for domain registrars to switch over.
Either way, I'm trying to set up Route 53 so that when users go to myapp.example.com they get routed to a specific EC2 instance of mine.
So I go into Route 53 and clicked Create Hosted Zone and Route 53 created two DNS records for me:
A NS (Name Server) record that has 4 different values, all of the form ns-<X>.awsdns-<Y>.<TLD>, where <TLD> is .com, .net, .co.uk, etc.; and
A single SOA (Start of Authority) record
I'm pretty green when it comes to DNS setup, I'm hoping I can just log into DotEasy's admin panel and update myapp.example.com's DNS settings to point to one of these records, but I'm not sure which ones I need to use. DotEasy's UI has fields that allow me to enter/change a primary, secondary, third and fourth DNS server hostname.
So I have two issues here:
Configuring Route 53 to route traffic over port 9200 to a specific EC2 instance (ultimately this will be an ECS custer or ELB load-balanced URL but for now its just a single EC2). I assume I need to write my own Zone file or perhaps Route 53 can create one for me?; and
Configuring DotEasy and/or Route 53 so that requests to https://myapp.example.com:9200 get forwarded to whatever resource/mapping was created above in Step 1
Any ideas how I can accomplish this?
DNS and HTTP are different protocols.
After you create an ELB attach your instances and within your DNS provider just create a CNAME pointing to the public address of your ELB, for example:
myapp IN CNAME elb-nme.us-west-2.elb.amazonaws.com
To respond request on port 9200, you need to configure the ELB for doing this, but this has nothing to do with the DNS.

I have a load balancer at this URL, which points to a Beanstalk application running at this URL. Currently, it just returns the current time.
I'm trying to make the application available at squadify.me, a domain name I own, via the load balancer.
After following this guide to create the necessary Route 53 record, I was expecting to be able to access the application (via the load balancer) at squadify.me. Am I missing something? The Route 53 records I currently have in place are shown below.
A Registered Domain in Amazon Route 53 will be assigned a set of four Nameservers. The Nameservers reside in different top-level domains, such as .co.uk, .net, .org and .com.
The server numbers are randomly (but very specifically) chosen for each domain. It is important that the name servers associated with your domain are the same as the domain names listed in the NS record for the domain.
To see the correct servers to use, go to Registered Domains, select your domain and choose "Add/edit name servers". If they are different to the NS record, then edit the NS record to match the nameservers displayed.
I am confused on the process of how to point a subdomain of an EC2 instance which is being run behind an ALB. The Target Group has port 80 which will then Redirect traffic to 443 and then a second Target Group which has the SSL certificate for 443. I have read online that I would need to create a hosted zone in Route 53 of the subdomain (e.g. apples.ilovefruits.org) and setup an ALIAS of the ALB. My domain and subdomains are hosted on Bluehost. The error I receive on the website to enter is a "403 Forbidden":
Would appreciate any help on this to get this to work.
UPDATE:
Should I replace the NS records of Route 53 with Bluehosts NS records?
I have read online that I would need to create a hosted zone in Route 53 of the subdomain (e.g. apples.ilovefruits.org) and setup an ALIAS of the ALB.
That's not true. You can delegate a subdomain and create an ALIAS record in Route 53, or you can create a CNAME record within your current dns provider.
An ALIAS record is an A record that will automatically resolve to an IP for the ALB without an intermediate CNAME lookup. This is great, but by no means necessary. An ALIAS record is a Route53-specific integration to other AWS resources.
Delegating a subdomain to route53 - at the cost of $0.50 a month plus a few cents per millions of requests - makes it more convenient to create with AWS dns records within that subdomain. It's especially useful if you're creating a lot of dns records that point to things in AWS. Creating records in your current DNS provider by hand is often an adequate solution until you're creating more than a few.
A route53 subdomain is also convenient if you're going to use ACM, amazon's cert issuing service. These certs are free, secure, and - if you use DNS validation - can renew automatically. If the domain of the certificate is in route53, the aws console for ACM will have a button to automatically add the validation record - convenient, right? But you can create the same record in any DNS provider, so again, until you're doing it a few times a week, the manual approach isn't so bad.
If you were to create a CNAME, do so in your current dns provider. Create a CNAME record whose name is your desired DNS name, and the value value is the ALB's dns name provided in the ALB details in the web console. This functions fine.
If you did want to delegate the domain, start by choosing the subdomain and creating its zone in Route 53. Take note of the 4 nameservers under the NS record there. These servers are ready to respond to requests for the subdomain, but nobody's going to ask them until you add these servers to your current dns provider as NS records for the subdomain. Then, public queries for the subdomain will be referred (or "delegated") to the amazon servers.
UPDATE: Should I replace the NS records of Route 53 with Bluehosts NS records?
No, The NS records for the zone in Route 53 are ready to serve queries for your zone, but that record is not what points any queries to those servers. The record that delegates the subdomain is in the parent zone (eg ilovefruits.org). Changing that NS record essentially does nothing. Above, we're *adding new * NS records for the subdomain, not changing anything that already exists for the parent domain.
If you're curious, the same is true of ilovefruits.org itself. In that case, the domain registrar also provides NS records for ilovefruits within the .org domain. As the domain registrant, you get to choose which servers these are. You could migrate your dns to amazon by changing these settings with your registrar. But strange as it may seem, even then, the NS records for the domain within that zone aren't being consulted for most dns lookups. DNS happens from the top level out, so .org is the domain that points to ilovefruits.org; it cannot, of course, point to itself!
Don't change the NS records of the root of your dns zone unless you're sure you know what you're doing. They aren't part of normal dns lookups and will be set appropriately by the dns provider, even if your domain hasn't delegated any dns queries to them.
The error I receive on the website to enter is a "403 Forbidden":
This has nothing to do with DNS and you should diagnose it separately.
I have purchased a domain name through ROUTE 53.
2) I have created a EC2 instance and put my web application inside it that is supposed to be hosted.
3) I have configured the Gunicorn and nginx as my WSGI and web server.
How to use the purchased domain name to integrate with my application to see over the internet. I have seen many documents post on stackoverflow, and youtube videos. But I am not able to get the clear picture of what am suppose to do next.
I get that once the domain is registered I have 4 ns records generated inside the ROUTE 53. But where to use them? how to configure them.
It be helpful if somebody can give me exact steps to perform the tasks.
Thank you,
Route53 is similar to other DNS servers with extra features, in your case, you will need to assign your ec2 instance a public IP address and to be safe an Elastic IP to avoid IP change on reboot, then you need to grab this public IP and assign it to your domain root A record and www CNAME record to point to that domain

Normally it's not required but it's helpful to control your DNS configuration from route 53 instead of the DNS registrar.
Create Hosted zone in route 53, for example if your domain name is example.com then create Hosted zone in route with name example.com, it will generate name server record.
Open newly created hosted zone and copy Name server (NS) record and replace the NS record in your DNS setting.
When you create a hosted zone, Route 53 automatically creates a name server (NS) record and a start of authority (SOA) record for the zone. The NS record identifies the four name servers that Route 53 associated with your hosted zone. To make Route 53 the DNS service for your domain, you update the registration for the domain to use these four name servers.
Add these record in DNS Name server, for example the below one is used for Godaddy

I am new to AWS Route53 and trying to brush up some of the basics. I have a question that might sound silly.
Lets say i have a public load balancer created with its DNS (AWS auto generated). Now i went ahead and got my corporate company to create a CName for the actual ELB A record, so say that CNAME is www.my-website.com.
Now when users start browsing www.my-website.com, their router DNS directly know where this public www.my-website.com is hosted and then once the DNS resolution happens, the request is directly forwarded to my ELB that has that CName to it.
Now all this is good but i would also like to play with Route53 here, so i go ahead and use Route53 to create a hosted zone and add my domain www.my-website.com under it and then create a record set with alias pointing to my actual ELB followed by rest of the configuration.
Now when someone hits www.my-website.com on their browser will the request directly go to the ELB or go to Route53 that will then route it to that ELB?
A summary of what these services provides is below:
Route 53 is a DNS Provider provided as a service by AWS. The functionality you're describing using is to store your DNS records within it for resolution.
An ELB is an appliance to distribute traffic across multiple nodes.
With your records in Route 53 the below journey takes place:
When a client in the browser attempts to go to www.example.com it will first check in its internal cache for any previously stored values for the domain, if theres a value it will be evaluated against a TTL to see if it has been expired.
If no value or expired the client will connect to the root domain, then the top level domain continuing until it finds the DNS provider for your domain (. -> .com. -> example.com..
Once it finds this DNS provider it will query for your domain, if it matches it will return the resolution value and the TTL.
If the value is that of a CNAME (such as an ELB) this process will begin again to resolves the IP address(es) for your hostname. This IP address will be cached by your local client.
If you're using Route 53 and an ELB one advantage would be to use Alias records they actually set your domain record to the IP address which improves the speed of DNS resolution.
So in summary Route 53 is only contacted if the client does not know the resolution value for your domain.
I have registered the domain duhastdiewahl.org at Amazon AWS Route 53.
I do it step for step like this:
http://share.pho.to/AAUSM
Create Hosted Zone (NS/SOA-Record default)
Add A-Record to my elastic ip adress for my EC2-Instance
Unfortunately if i ping the adress the name can't be resolved and tools like http://mxtoolbox.com says that the nameservers couldn't be found.
Can anybody tell me what is wrong?
Thank you for your support :)
Your nameservers are configured incorrectly in Route 53 "Registered Domains" -- they don't match the servers assigned to you in "Hosted Zones."
Route 53 is two different services -- domain registration and DNS hosting -- and the settings between the two of them need to match. One possible cause of a mismatch is deleting and recreating your hosted zone. That wouldn't fix anything, but a lot of people seem to try it anyway. When you do that, it assigns four new name servers do your domain for hosting -- but the registrar service doesn't learn about this, because there's not necessarily a connection between the two services. You could register a domain on one AWS account, and host the DNS on another, if you wanted -- the two "sides" of Route 53 are essentially independent.
To fix:
In the Route 53 console, click Hosted Zones, click your domain, and make a note of the assigned 4 name servers. Don't change anything here.
Click "Registered Domains."
Select your domain.
Choose "add/edit name servers."
Enter the correct values for the assigned Route 53 name servers, which you obtained from the Hosted Zones screen.
