DNS Question: What about that AAAA record

A stands for address. Address record. That’s good.

So… what does AAAA stand for…? Why not AddressAddress, or AAAAAAAAA? Why AAAA?

What’s the background on this ugly name of a post?

A IPv6 address is 128 bits, 4 times larger than an IPv4 address (32 bits).

So, 4 times an A record is an AAAA record.



well, since IPv6 is at least 4 times better than ipv4, it deserves at least a 4-times better DNS record type. Be thankfull they didn’t go for AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA to indicate the improvement in address space.

Seriously, I got nuthin on this. the RFC doesn’t give any insight.

Ah, OK, thanks.
