What is DNS ?
DNS (Domain Name System) is a service that translates domain names into IP addresses. Users can easily remember domain names, but he computers understand IP addresses that’s why we need DNS. For example, without this service, you have to type '185.60.216.35' in your browser instead of www.facebook.com to access Facebook. IP - Domain mappings are kept on DNS servers. You can query those matches on s4e.io
There are two types of IP addresses IPv4, and IPv6. IPv4 address looks like these:
8.8.8.8
127.0.0.1
255.255.255.255
IPv6 addressed looks like these (all of them are the same IP):
::ffff:808:808
0:0:0:0:0:ffff:0808:0808
0000:0000:0000:0000:0000:ffff:0808:0808
What is AAAA RECORD?
DNS AAAA record maps a domain to an IPv6 address. “A record” stands for “address record” whereas an IPv4 address is 32 bits long. So the difference between A record and AAA Record is that AAAA record is 4 times bigger than A record. AAAA records holds IPv6 address. You can have both IPv6 and IPv4 addresses. To do that, you have to set both A and AAAA record.
In order for people to access your domain name with IPv6, your domain name needs to have a correct AAAA record.
You may be seeing IPv6 addresses much less frequently. But IPv4 addresses are running out. For this reason, IPv6 addresses, which are much more numerous (because of 128 bits in length), are being used. There are even sites that only supports IPv6!
DNS AAAA record must have a valid IPv6 addresses. Usually, domains have only one IPv6 address in their AAAA records. But it can be more than one to provide redundancy.
How To Do DNS AAAA Record Lookup?
Pretty Simple. Use our free DNS AAAA Record lookup tool online. Write your domain on the form at top of the page.
if you are using a Linux or an OS X operating system, open terminal and type dig -t aaaa yourdomain.com. If your domain has a valid A record, it would look like that:
dig -t aaaa s4e.io
;; ANSWER SECTION:
s4e.io. 300 IN AAAA 0:0:0:0:0:ffff:7f00:1
If you are using Windows open powershell and type Resolve-DnsName -Name yourdomain.com -Type AAAA
If DNS AAAA Record doesn't look the way you want, there are a few things you can do.
- Make sure your domain name AAAA record is in the right place. To do this, check NS Record. Then make sure that the NS server is correct.
- If your NS server looks correct, enter an AAAA record on that server for your domain. If you are using providers such as godaddy, linode, digital ocean, bluehost, hostgator, you can control these operations from their user console.
- DNS changes may take some time. Check back after a while.
- The AAAA record looks correct, but you still can't access it. Check the service configs (such as web server settings).
