DNS AAAA record (IPv6) on gitlabs domains

Hi,

now gitlab.com (and on other related domains as packages. ci.) domain provides DNS record for type A (IPv4). But not for AAAA (IPv6)

dig gitlab.com AAAA +noall +answer                                                                

; <<>> DiG 9.10.2-P3 <<>> gitlab.com AAAA +noall +answer
;; global options: +cmd

I run into this trouble on machine connected only via IPv6. Is there any reason to not allow IPv6 in 2015? Could you provide AAAA record to your DNS and allow IPv6 connectivity?
