I recall that 3M was originally mmm.com because they wouldn't allow a number
to start a domain.

/me runs whois mmm.com

Yep,  Created on..............: 1988-10-31.

but wait, 3m.com  Created on..............: 1988-05-27.

So was the digit as first octet a limitation with some OS or software (BIND,
sendmail, gopher?) or do I have brain-fade?
