    Want to find out who owns an ASN number?

    Utilities, Whois, Select "User Defined" (type whois.arin.net in the field next to
    it ) or select IP Address (arin) for the country/method, and enter the ASN
    number where you would normally type the domain.

    Nice that you see all the netblocks assingned to that entity too!

    Of course a one of your better whois services
    offers ASN lookups as well but what the heck -
    its nice to have it right at your own desktop.

    Interesting tip. :)

    The Whois protocol supports several other tricks also, see here for some examples.

    Sorry for asking a stupid question, but why would this be useful to an average user?
    I understand using ARIN for looking up IP address ownership and whois for domain name ownership.
    How do you find out the ASN for a target that you want info on?
    Where is the ASN found?

    Thanks

    Re: Devinco and wayne - ASN and PE - AWESOME!!!

    Devinco - certainly not a stupid question.
    If you read mailing lists of Network Operators (NANOG for one) they talk in
    ASN quite often as they handle huge networks - they are often ISPs,
    sometimes universities, or very large corporate network operators.

    They live and die by huge BGP routing tables, peering via multiple providers,
    and massive, global, networks. I can use this to understand their
    conversations, and their customers, when they discuss problems.

    Wayne - re: the NICNAME service - the addresses mentioned in the
    updated RFC812 you posted -

    NOTE DON'T MESS WITH MILITARY ADDRESS SPACE -
    THEY WILL COME AND GET YOU


    This is Defense Information Systems Agency

    Anyway I couldn't get the whois in PE to connect.

    Found the change in service notification but no joy there either.

    How do I access NICNAME in PE?
    Can we mere civilians access it at all??
    Is NICNAME even in existence today?

    Side note - while reading around I came across interesting comments about
    ARPA - back in the day when infosec was a non-issue even to the military -
    check this out:

    and
    YOU COULD LOGIN TO A US MILITARY FTP SERVER ANONYMOUSLY!!!!
