What is the purpose of DNS AAAA record?
An AAAA record is used to find the IP address of a computer connected to the internet from a name. The AAAA record is conceptually similar to the A record, but it allows you to specify the IPv6 address of the server, rather than the IPv4.
What is an AAAA DNS record?
An AAAA Record (quad A Record) is another type of DNS Record that points a domain or subdomain to an IPv6 address, so that when someone types that domain or subdomain in the address bar, the browser knows where to go.
What is TTL in DNS settings?
DNS TTL (time to live) is a setting that tells the DNS resolver how long to cache a query before requesting a new one. If 100 users visit the site in that period, they will all see the same thing, until the resolvers update their TTL.
What is A and AAAA in DNS?
A and AAAA records are equally important when it comes to resolving DNS. The difference lies in that A records is used to resolve a hostname which corresponds to an IPv4 address, while AAAA records are used to resolve a domain name which corresponds to an IPv6 address.
Is AAAA record necessary?
No, it is not necessary to create an AAAA record for your website as long as most traffic runs over IPv4, but I would argue that it probably is beneficial for the deployment of IPv6 to have more sites support the protocol.
What is the difference between A and Cname DNS records?
Difference Between A and CNAME An A Record maps a hostname to one or more IP addresses, while the CNAME record maps a hostname to another hostname.
Can I have 2 DNS A records?
You can do a lot with A records, including using multiple A records for the same domain in order to provide redundancy and fallbacks. Additionally, multiple names could point to the same address, in which case each would have its own A record pointing to that same IP address. The DNS A record is specified by RFC 1035.
How do I find TTL settings?
The easiest way to look up TTL settings is to use the dig utility available on Linux, Unix, and Mac OS X. This will return the DNS information (including TTL values) for the domain name.
What should I set my TTL to?
Generally, we recommend a TTL of 24 hours (86,400 seconds). However, if you are planning to make DNS changes, you should lower the TTL to 5 minutes (300 seconds) at least 24 hours in advance of making the changes. After the changes are made, increase the TTL back to 24 hours.
