RFC791 is about protocol bits. 192.168.050.0 and 192.168.50.0 would

However, by convention leading zeros aren't used, at least partly
because another convention says a leading 0 implies octal. In a BIND
zone file, a leading 0 in an A record causes BIND to complain "not a
decimal dotted quad".
I would say don't allow them.
I agree. I happened to stumble upon this in my early years, in
an attempt to nicely format a host file. 050 would be 5 times 8
equalling 40. I think it was SCO unix but am not sure.
