Subject: [PATCH] inspector: harden IP address validation again
Use inet_pton() to parse IP addresses, which restricts IP addresses
to a small number of well-defined formats. In particular, octal and
hexadecimal number formats are not allowed, and neither are leading
zeros. Also explicitly reject 0.0.0.0/8 and ::/128 as non-routable.
