casually looking through what seems to be a list of the oldest .com registration still around, I came across 3com.com, registered, according to whois on 11-dec-1986. Been a while :)
Thing is I had this vague impression that domain names weren't allowed to begin with a number until later than that. Upon checking, RFC 952, published in October 1985 had the starting-number restriction and it wasn't until RFC 1123 (Oct 1989) that this got relaxed. Anyone around remember how 3com.com got registered ahead of it seemingly being a valid domain name (and again, this is in itself a bit confusing as RFC 952 introduces the restriction for hostnames and domain names, and RFC 1123 only seems to lift the restriction for hostnames)

Anyway just curious
