Perl: 5.14.4 OS: SunOS dev1 5.11 omnios-d3950d8 i86pc i386 i86pc Solaris Function: is_public_ipv6(), internally using _slow_is_ipv6() Input ":11" Error: "Bad arg length for NetAddr::IP::Util::sub128, length is 0, should be 128" While parsing some HTTP headers for ips with is_public_ipv4() and is_public_ipv6(), I came across the input and resulting error listed above. It passes the parsing of _slow_is_ipv6. When fed to NetAddr::IP->new6(), the result is undefined. Passing undefined to $network->contains() causes the error. I have attached a short test script and a patch. The patch fixes both the _slow_is_ipv6 such that it fails leading single colons as invalid, as well as returning early if in is_[network]_ipv[4,6]() subs if NetAddr::IP->[new,new6]() is undefined.
