This is an IPv6 host only, I don't thing this should be considered as
weird nowadays. Here is the /etc/hosts file, I do not spot an issue:

##
## THIS FILE IS UNDER PUPPET CONTROL. DON'T EDIT IT HERE.
## USE: git clone git+ssh://$USER@puppet.debian.org/srv/puppet.debian.org/git/dsa-puppet.git
##

127.0.0.1       localhost
2a02:16a8:dc41:100::238        x86-conova-01.debian.org x86-conova-01

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
