Fetch IP whois data from terminal using telnet
In a previous article we saw how to fetch the whois data of a domain from the terminal. Now here we shall see how to perform a whois for an ip address from the terminal.
Get your ip address from ipmango.com.
I got this IP : 18.104.22.168
The information about any ip or ip range is stored in the Regional Internet Registry.
The 5 internet registries in the world are
1. APNIC - India , China , Australia Whois server : whois.apnic.net 2. AFRINIC - All of Africa continent Whois server : whois.afrinic.net 3. ARIN - Usa and Canada Whois server : whois.arin.net 4. RIPE NCC - Greenland , Russia , Europe and middle east Whois server : whois.ripe.net 5. LACNIC - Mexico and South America continent Whois server : whois.lacnic.net
Perform the Whois query
Open your terminal and type :
desktop:~$ telnet whois.apnic.net 43 Trying 22.214.171.124... Connected to whois.apnic.net. Escape character is '^]'. % [whois.apnic.net node-2] % Whois data copyright terms http://www.apnic.net/db/dbcopyright.html
Now we are connected to the whois server. Now enter the IP address and hit enter
126.96.36.199 inetnum: 188.8.131.52 - 184.108.40.206 netname: BB-2-2 descr: Broadband Project2.2, O/o DGM BB, NOC BSNL Bangalore country: IN admin-c: BH155-AP tech-c: DB374-AP status: ASSIGNED NON-PORTABLE mnt-by: MAINT-IN-DOT mnt-irt: IRT-BSNL-IN changed: [email protected] 20110218 source: APNIC route: 220.127.116.11/20 descr: BSNL Internet country: IN origin: AS9829 mnt-lower: MAINT-IN-DOT mnt-routes: MAINT-IN-DOT mnt-by: MAINT-IN-AS9829 changed: [email protected] 20060404 changed: [email protected] 20060404 source: APNIC person: BSNL Hostmaster nic-hdl: BH155-AP e-mail: [email protected] address: Broadband Networks address: Bharat Sanchar Nigam Limited address: 2nd Floor, Telephone Exchange, Sector 62 address: Noida phone: +91-120-2404243 fax-no: +91-120-2404241 country: IN changed: [email protected] 20021108 mnt-by: MAINT-IN-PER-DOT source: APNIC person: DGM Broadband address: BSNL NOC Bangalore country: IN phone: +91-080-25805800 fax-no: +91-080-25800022 e-mail: [email protected] nic-hdl: DB374-AP mnt-by: MAINT-IN-PER-DOT changed: [email protected] 20110218 source: APNIC Connection closed by foreign host.
Now we get plenty of information about the IP address , like its ISP , IP Range , Country and so on.
Now lets try a different IP say : 18.104.22.168
desktop:~$ telnet whois.apnic.net 43 Trying 22.214.171.124... Connected to whois.apnic.net.

We see that APNIC did not provide any information about this IP, but says that this IP is allocated to ARIN registry.
So we perform whois query on the arin whois server that is whois.arin.net
So now the ARIN whois server gives the required information. Similary the whois details of IPs of RIPE , AFRINIC and LACNIC regions can be found.
