We have a domain mydomain.com, which we have registered with a UK registrar. We are using Amazon's Route53, and this domain has been added in Route53 and is using the name servers as follows;
ns-558.awsdns-05.net
ns-1755.awsdns-27.co.uk
ns-466.awsdns-58.com
ns-1343.awsdns-39.org
I've added the relevant A records for www etc to point our elastic IP to this domain.
We are also running MailEnable on this EC2 server (running Windows 2012). The MailEnable server is asking for me to enter DNS addresses (Check and configure DNS settings), I assume it will use when sending email.
My question is what DNS addresses / servers can I use ? Can I use
ns-558.awsdns-05.net
ns-1755.awsdns-27.co.uk
ns-466.awsdns-58.com
ns-1343.awsdns-39.org
You can see the DNS address(es) in the screen shot below.
You can't use those Amazon servers because they're authoritative-only (they'll only tell you about domains they know about, instead of acting as a recursive proxy). You can use Google's public DNS servers at 8.8.8.8 and 8.8.4.4 for that field.
(original answer below)
You need to create an A record that points at the elastic IP assigned to your mail server (for example, mail.yoursite.com points at 1.2.3.4). Then, you'd create an MX record for yoursite.com that points at mail.yoursite.com. Finally, I believe you would give MailEnable mail.yoursite.com, but I'm not 100% sure on that.

I have deployed a django based website on my AWS lightsail instance. the web address has a port 8000 (:8000). I own a domain on (host =fatcow.com). I have created a hosted zone on AWS and pasted the ns values to my provider(factor)'s Nameservers values. In the amazon route53, I have created a new record with a simple redirect A ipv4 and entered the resolver IP address value - my web address with port value. it doesn't work.
Also, I have read that the redirect will not work for its with port numbers. I have tried redirecting my domain to the static ip, then created another hosted zone record trying to redirect the static ip to the ip+port value - error pops up saying it is not a valid address.
I currently use the development server provided by django as it is a personal website and currently it will not have a lot of traffic - portfolio website.
Also, on my fatcow.com domain settings, the Nameservers are updated and in the whois values, new Nameservers are seen. I have only added the 4 NS values. AWS also created SOA ip values but I was not able to add them to the domain (Inputs were not taken by fatcow ).
In the NSLookup website, I can see NS values and SOA values which are on the AWS hosted zone but A records show none.
Edit: sorry for the confusion. my domain is www.chandradhar.com. I'm not a web dev but I'm trying to deploy a django based portfolio website. I have added Amazon Lightsail DNS nameservers to my domain (host=fatcow.com). the web address is :8000 port. Without the port number, the website isn't loading at all. Only with the port number along the static IP, the website loads. 'A' record isn't taking the port number. I did add a SRV record with the port number(in AWS route 53) but still doesn't work. when checked from the website nslookup.io, the nameservers are updated correctly
Not reproduceable.
> host fatcow.com
fatcow.com has address 65.254.254.33
fatcow.com mail is handled by 10 mail.fatcow.com.
Most probably your changes in DNS have already propagated.
Steps to successfully deploy one or more websites on lightsail AWS when the domain is on another website like godaddy/fatcow.
Create a dns zone in the networking section of the lightsail instance.
Copy the name servers from the dns zone and paste it in the name servers section of the domain provider (fatcow/godaddy) - it might take upto a day for the values to get updated - i used nslookup.io to see if my nameservers were updated.
Create 'A' records and SRV records pointing to the static ip of the lightsail instance.
Install Nginx
Create a simple script with the (name of the website).conf in the conf.d folder/available sites folder
Add the following script:
server
{
listen 80;
server_name domainname.com;
location / { proxy_pass http://ipAdd:PortNum;
}
}
Repeat the same code block with different domains and redirect ports. I guess we can also use 301 redirect to achieve the same.
This might or might not be the proper way of achieving what I required but it'll work.
I have migrated my website to the Google Cloud servers. I have pointed the old DNS to the Google DNS and I have setup the DNS zone with an A record for the main domain pointing to the IP of the Google Cloud server and a CNAME record for the www subdomain. However, when I type the domain name in the browser, it loads the Google Cloud IP, but the browser doesn't show the domain name but the IP address.
You need only one DNS entry for the instance;
www aliased (A) to the (external) IP address of the server.
From your description I guess that you configured your Cloud DNS in a correct way and that your domain registrar is pointing to GCP DNS servers:
nameServers:
- ns-cloud-a1.googledomains.com.
- ns-cloud-a2.googledomains.com.
- ns-cloud-a3.googledomains.com.
- ns-cloud-a4.googledomains.com.
Nevertheless make sure your DNS configuration looks similar to this:
If you need to add some records to your DNS here's some usefull documentation on how to add records to do it. You can use both console or gcloud utility for this.
You may also have a look at the documentation on how to migrate to GCP from other providers.
But - I suspect some tricky-webserver configuration issue here. Why ?
You pointed out that you can reach your website - but instead of domain name you see a real IP of your site in the browser. That may be the result of a specific configuration that "redirects" you to a certain IP after detecting you used domain name to get to the server.
Please inspect your webserver's configuration and try to point out a real cause of this.
I have bought a domain name from GoDaddy and would like to host it on an EC2 instance. I have created the instance and have installed apache. I have added an index.php with phpinfo(); and it is showing correctly when I access the public IP on browser. Now I would like to point my domain name to this instance. For this I have added an A RECORD at Godaddy DNS configuration. But when I access the doamin, it is showing
ERR_CONNECTION_TIMED_OUT
message in the broswer. Is there any additional settings I need to do ?
What you did is what it is needed. SO if it is not working then then you have to check everything again :
- check (for example with ping) if the domain is in fact resolving to correct IP address (from your computer and from instance for example to use different DNS servers). You can also use host command (for example host www.mydomain.com 8.8.8.8 - it will use google's dns (8.8.8.8) as the source of truth
- check if Security Group in aws allows inbound traffic (that's probably true as you can reach the instance directly)
- try to connect from different network (again this should not be problem as IP is reachable using IP).
you can also post the domain name and requested Ip so we can check this for you ;)
I am a newbie to AWS. I have read about DHCP Option Set and also about Route 53. However, I do not understand clearly about the similarities and differences between them.
In my understand, both help us customize DNS name, and DHCP is a component of VPC, but Route 53 is an AWS service, am I right? If yes, is there any differences between them? In which case we use DHCP? In which case we use Route 53 instead of DHCP Options?
Route 53 is a DNS service - this allows you to publish hostnames and their associated ip addresses to the world at large. For example, on a simple level, I might publish the following:
www.example.com A 123.45.67.89
This would tell internet users around the world that the server www.example.com can be found at ip address 123.45.67.89
This is hugely simplfied, but think of Route 53 as a part of a distributed, decentralised database of hostnames and ip addresses.
DHCP is used by a host to get its network configuration at startup. When a machine, or vps, or ec2 instance starts up, it will make a DHCP request for its network configuration, and a dhcp server will respond, giving the host a number of parameters, but at a minimum an IP address. The dhcp may then register this ip address/hostname combination in DNS. DHCP options are extra network configuration parameters, for example, telling the host that is part of the domain example.com, that its default router is 10.0.0.2, or any number of other options. These affect the way the host configures itself to talk to the network.
DHCP in your VPC is used to automatically assign domain names to your EC2 servers that are generated by Amazon. The domain names will look like ec2-public-ipv4-address.compute-1.amazonaws.com
Route53 is a DNS service for assigning custom domain names that you own to your AWS resources. If you wanted to assign someting like myapp.mydomain.com to your EC2 server, you wouldn't be able to accomplish that with DHCP, you would need to use a DNS service like Route53.
I am new in the Amazon EC2 world, I just created an app, that is located URL like this:
http://ec2-54-123-45-678.compute-1.amazonaws.com:8080
This is generated URL by Amazon EC2.
Now I would need to use my own domain name, so when I would access www.my-domain-name.com, I would like to see the content from
http://ec2-54-123-45-678.compute-1.amazonaws.com:8080
I bought the domain name on Godaddy.
Is there any way to do this in Amazon AWS dashboard or do I need to set it up in Godaddy system?
Thanks
I am answering on a more general level because I stumbled upon this thread when setting my custom domain.
In Amazon I created an instance and associated an IP to that instance. You were able to access it by typing in the amazon url
I actually used Media Temple not GoDaddy, but it will be similar. I went to the zone file and added that public url to the www
And as you can see, here is my blog actually working on the custom domain.
I set the wildcard because that way, no matter what someone types, if it is not set, then they will still see the site.
EDIT
For the root URL you should be entering your elastic IP and setting that as an A record.
First you need to set an ElasticIP for associated to that instance.
Then point the DNS entry of "www" for "my-domain-name.com" to the IP assigned in the step above.
Where you manage your DNS is another thing, can be in GoDaddy or in AWS Route53. You must adjust the delegation DNS in the "my-domain-name.com" register. Ex: your domain can be registered with GoDaddy but its delegation DNS point to Route53 so you can manage the domain from your AWS Console.
In order to setup DNS mapping you can map the existing IP 54.123.45.678 to ex: www.my-domain-name.com.
However, as you are running tomcat which is running at 8080 you need to forward the the request to the tomcat using Apache. So that you can visit www.my-domain-name.com without port 8080. If you are using linux box install Apache, apache-modjk and then configure sites.
