Netflix, amazonaws and IPv6?
[ca] Shadow Hawkins on Wednesday, 15 May 2013 01:42:45
Up until recently I have been able to use Netflix over IPv6, but now I am finding that the servers aren't appearing with an AAAA entry in the DNS records. Does anyone know if amazonaws.com or Netflix changed anything? As an example, if I lookup movies.netflix.com, this resolves (at the time of lookup) to nfzuul-merchweb-usca-frontend-1524277266.us-west-2.elb.amazonaws.com. and this has no AAAA record. This issue started happening about a week ago.

DNS is a location-based thing nowadays, thus depending on your source address and the destination of your query you will get different results, from my POV somewhere in Europe:
$ dig +short movies.netflix.com aaaa dualstack.merchweb-eu-frontend-616370852.eu-west-1.elb.amazonaws.com. 2a01:578:3::b022:b900 2a01:578:3::2e89:5832 2a01:578:3::b022:ef39
From a view in the US:
$ dig +short movies.netflix.com aaaa dualstack.merchweb-usca-frontend-958509217.us-east-1.elb.amazonaws.com. 2406:da00:ff00::3210:d5da 2406:da00:ff00::1715:6d52 2406:da00:ff00::1715:7eb3 2406:da00:ff00::1715:cf7e 2406:da00:ff00::6b15:d946 2406:da00:ff00::ccec:e713
Strange that it says 'us-east' there, I am sure that location is on the west coast :) Ah, when another one:
$dig +short movies.netflix.com aaaa nfzuul-merchweb-usca-frontend-1524277266.us-west-2.elb.amazonaws.com.
So it seems that the us-west ones are not having AAAAs for the time being...
