Fellow networkers,
=A0
Team Cymru is happy to announce the availability of a public whois
server dedicated to mapping IP numbers to ASNs, located at
whois.cymru.com.=A0 You can find the link to this tool at:
=A0
http://www.cymru.com/BGP/whois.html
=A0
This link has been added to our main BGP data page available at:
=A0
http://www.cymru.com/BGP/index.html
=A0
We have also extended the functionality of this daemon to support BULK
IP submissions for those who wish to further optimize their queries with
netcat.
=A0
Following is a quick overview of how to use it:
=A0
$ whois -h whois.cymru.com <IP>
=A0
Where <IP> is replaced by the IP you'd like to map, like so:
=A0
$ whois -h whois.cymru.com 4.2.2.1
=A0=A0=A0 ASN |=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 IP | Name
=A0=A0 3356 |=A0=A0=A0=A0=A0=A0=A0=A0=A0 4.2.2.1 | LEVEL3 Level 3 =
Communications
=A0
You can also include port information, and/or timestamps in your
queries.=A0 Be sure to include quotes around your queries, or the daemon
will interpret your request as multiple lines:
=A0
$ whois -h whois.cymru.com "4.2.2.1 -0600 GMT"
=A0=A0=A0 ASN |=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 IP =
|=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 Info | Name
=A0=A0 3356 |=A0=A0=A0=A0=A0=A0=A0=A0=A0 4.2.2.1 |=A0=A0=A0=A0=A0=A0 =
-0600 GMT | LEVEL3 Level 3
Communications
=A0
For instructions on how to submit BULK queries via netcat, simply issue
the following command:
=A0
$ whois -h whois.cymru.com help
=A0
We hope you find this tool useful.=A0 Stay tuned for more features!=A0=20
=A0
If you have any comments or suggestions as to how we might improve this
service, feel free to let us know!
