That's not correct. Don't confuse the (long obsolete) RFC 950 class A/B/C
subnetting with the strings accepted by inet_aton. RFC 791 doesn't define or
use any string notation for IP addresses (it defines them as sequences of
four 8-bit bytes), and RFC 1020 uses a notation which is not consistent with
inet_aton.
