What is DNS A and AAA?
Summary of DNS A and AAAA Records
What is DNS Type A:
The “A” stands for “address” and this is the most fundamental type of DNS record: it indicates the IP address of a given domain. For example, if you pull the DNS records of cloudflare.com, the A record currently returns an IP address of: 104.17.210.9.
What is an example of a AAAA record in DNS:
AAAA records are similar to A records and are used to point a domain or subdomain to an IPv6 address. For example, if you query the AAAA records of google.com, it currently returns an IPv6 address of 2607:f8b0:400a:800::200e.
What is the difference between DNS AAAA record and CNAME:
Most used DNS records and what they influence:
AAAA: inserted is IPv6 address. Influences shown websites (website browser prefers IPv6). CNAME: inserted is the domain name and only for a subdomain. Redirects subdomain on wanted domain.
Can I have both A and AAAA records:
As with the A records, you can use multiple AAAA records for the same domain in order to provide redundancy. Multiple names could point to the same address, in which case each would have its own AAAA record pointing to that same IP address. The DNS A record is specified by RFC 3596. Cached
What are the 4 four types of DNS servers:
All DNS servers fall into one of four categories: Recursive resolvers, root nameservers, TLD nameservers, and authoritative nameservers.
What are AAAA records used for:
Like A records, AAAA records enable client devices to learn the IP address for a domain name. The client device can then connect with and load the website. AAAA records are only used when a domain has an IPv6 address in addition to an IPv4 address, and when the client device in question is configured to use IPv6.
What is the AAAA record used for:
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.
Why use AAAA records:
Like A records, AAAA records enable client devices to learn the IP address for a domain name. The client device can then connect with and load the website. AAAA records are only used when a domain has an IPv6 address in addition to an IPv4 address, and when the client device in question is configured to use IPv6.
Why use a CNAME instead of an A record:
General rules: Use an A record if you manage which IP addresses are assigned to a particular machine, or if the IP are fixed (this is the most common case). Use a CNAME record if you want to alias one name to another name, and you don’t need other records (such as MX records for emails) for the same name.
What are A and AAAA records respectively for:
A and AAAA DNS records
| DNS Record | Description |
|---|---|
| A | Maps domain names to IPv4 addresses |
| AAAA | Maps domain names to IPv6 addresses |
| CNAME | Redirects a domain to a different domain |
| PTR | Resolves IPv4 or IPv6 addresses to domain names |
What are the 3 types of DNS:
There are three main kinds of DNS Servers — primary servers, secondary servers, and caching servers.

What type of DNS should I use
Answer: Public DNS systems such as OpenDNS, Cloudflare, or Google DNS are better than the servers maintained by internet service providers. You should use public DNS servers as they offer maximum uptime, faster speeds, and increased security.
What does AAAA stand for in DNS
An AAAA record (sometimes referred to as a quad A) record gives the IPv6 (Internet Protocol version 6) information when a DNS query is performed. The A in this case stands for Address, similar to A records which resolve a domain namef or an IPv4 address.
Should I have a AAAA record
You need an AAAA record to ensure that your website or online resource can be accessed using IPv6 addresses. IPv4 addresses, the earlier type of IP address, are getting used up, making it vital to evolve to the newer IPv6 addresses.

What devices use AAAA
The AAAA battery can be utilized in a wide variety of electronic devices such as Microsoft Surface Pro Stylus, StreamLight Stylus®, Penlights, Flashlights, Mini flash lights, laser pointers, calculators, electronic games, motor toys, movie cameras, portable tape recorders, portable TV set, Bluetooth® headsets, glucose …
What is an example of a CNAME
CNAME stands for Canonical Name. A common example is when you have both example.com and www.example.com pointing to the same application and hosted by the same server.
When should I use a CNAME
CNAME records are typically used to map a subdomain such as www or mail to the domain hosting that subdomain's content. For example, a CNAME record can map the web address www.example.com to the actual web site for the domain example.com.
What is the difference between AAAA and A 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.
What is the difference between DNS Type A and AAAA
A Record vs.
A and AAAA or “Quad A” records are essential DNS records in the Domain Name System. The main difference is that an A record resolves a domain name to its corresponding IPv4 addresses, while an AAAA record resolves a domain name to its related IPv6 addresses.
What are the 3 sections of DNS
The DNS has three components: authoritative servers, recursive servers, and clients (resolvers). A client (resolver) is installed in any computer with TCP/IP software.

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.
What is the purpose of the AAAA record
Like A records, AAAA records enable client devices to learn the IP address for a domain name. The client device can then connect with and load the website. AAAA records are only used when a domain has an IPv6 address in addition to an IPv4 address, and when the client device in question is configured to use IPv6.

What does the acronym AAAA stand for network
Authentication, Authorization and Accounting. AAAA. Authentication, Authorization, Accounting and Address.
