Yes, and while interesting, a language spec isn't really what I was looking
for. I was hoping for an RFC, BCP, STD, or something like that (I'd even
take ISO or IEEE...).
I understand, but the language spec is the root of this particular
can of worms, I suspect all the way back to BCPL and earlier.
To be clearer, here is the ABNF from section 3.2.2 of STD 66, which
also seems to preclude leading zeros in IPv4 addresses:
IPv4address = dec-octet "." dec-octet "." dec-octet "." dec-octet
dec-octet = DIGIT ; 0-9
/ %x31-39 DIGIT ; 10-99
/ "1" 2DIGIT ; 100-199
/ "2" %x30-34 DIGIT ; 200-249
/ "25" %x30-35 ; 250-255
Note that IPv6 is a whole different can of worms, and the standard
notation for IPv6 DOES use optional zero padding.
