Description
Posted this to users@ceph.com, but didn't get a response.. give I think its a bug.. i'll raise it here.
I’m trying to download some ceph packages on a host which is IPv6 only.
Short version is, it’s not working.. and I think it’s because download.ceph.com isn’t configured to listen on IPv6?
The host I’m testing on is IPv6 only there is no v4 address configured.
$ host download.ceph.com
download.ceph.com has address 173.236.253.173
download.ceph.com has IPv6 address 2607:f298:6050:51f3:f816:3eff:fe50:5ec
$ wget https://download.ceph.com/rpm-hammer/el7/x86_64/repodata/repomd.xml

If it didn’t have an IPv6 address advertised our NAT64 would do its thing.. but because it has both advertised it always uses the v6 address then for some reason (could be config on our end) doesn’t NAT64 the IPv4 address.
I believe that if you're advertising the DNS, it should be listening as well.
As a workaround we have put the NAT64 address in /etc/hosts

Thank you for bringing this to our attention.
The DNS record has been updated and server has been configured to listen on its IPv6 address.
