Looks like a but in NetAddr::IP 4.034, it forgets to adjust the CIDR mask when converting an IPv4 address to an IPv6 notation: correct (NetAddr-IP-4.033): $ perl -le 'use NetAddr::IP; print NetAddr::IP->new6("127.0.0.0/8")' 0:0:0:0:0:0:7F00:0/104 wrong (NetAddr-IP-4.034): $ perl -le 'use NetAddr::IP; print NetAddr::IP->new6("127.0.0.0/8")' 0:0:0:0:0:0:7F00:0/8 Mark
