Hello,

i have tested from one subnet in our local AS network and got result

curl -4 'http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os'
http://centos.vpsnet.lt/centos/7.2.1511/os/x86_64/

everything looks fine

test 2 for ipv6

curl -6 'http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os'
curl: (7) couldn't connect to host

ping6 mirrorlist.centos.org

these test was made from 91.211.244.0/22 and if ipv6 from 2a05:7cc0::1/32

our ipv6 is working correctly:

ping6 2a05:7cc0::91:211:244:21
PING 2a05:7cc0::91:211:244:21(2a05:7cc0::91:211:244:21) 56 data bytes

test from other subnet: 185.34.52.0/22
