Does DNS allow numeric domain names? I presume ICANN wouldn't sell us the .91 TLD, but hypothetically it could be an awesome trick to weird out all those smartasses who think they know everything about IP address validation :)

There are numeric domain names, but no numeric TLDs. You can see all the current TLDS here: http://data.iana.org/TLD/tlds-alpha-by-domain.txt http://data.iana.org/TLD/tlds-alpha-by-domain.txt The only rule I can find is from RFC 1738 (http://www.ietf.org/rfc/rfc1738.txt http://www.ietf.org/rfc/rfc1738.txt) "The rightmost domain label will never start with a digit, though, which syntactically distinguishes all domain names from the IP addresses"

  would 75.748.86.91.mydomaininmysearchlist.com work?

    Yes. You can register a numeric domain also, like 123.com or whatever, though I assume at least all the 1, 2, and 3 digit ones are taken.
