Autonomous System Numbers and PE - AWESOME!!!

[ceegee]

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 (http://www.completewhois.com/)
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 (http://www.phys-iasi.ro/Library/RFCs/rfc954.htm) 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

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 (http://www.merit.edu/mail.archives/mjts/1991-09/msg00009.html) 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:

-{ Quote: "It may be FTPed from the SRI-NIC.ARPA host ... SRI-NIC.ARPA
supports "anonymous" login." }-and
-{ Quote: "may be obtained by FTP (or Kermit) from the NIC.DDN.MIL host ...
using login="anonymous" and password="guest"." }-
YOU COULD LOGIN TO A US MILITARY FTP SERVER ANONYMOUSLY!!!!

Thanks ceegee!
