AAAA and 100::
if you dont mind me asking, why a
AAAA here specifically and why this specific value?4 Replies
You needed a proxied record and we like to use
100:: (IPv6 discard address) for this. Since it's IPv6 that would mean an AAAA record
It's short and does what is needed 🙂
So that's our recommended address for these kinda dummy recordsright. any specific reason for using ipv6 over ipv4 though?
or is it just a common practice
Just shorter. You're free to use 192.0.2.1 (or really any other) as well with a A record
100:: is maybe a bit more accurate too since its meant for discarding traffic rather then 192.0.2.0 which is just test-net space meant for testing/documentation
Plus I think part of the idea is to use something that doesn't route anywhere. If a ton of people used 1.1.1.1 (which people used to use before it got blacklisted), and something went wrong with CF's Routing, you wouldn't want a ton of http requests to a real ip/service.
