Retrieve IP Address from URL – nslookup
September12
In unix/linux we have a utility called nslookup. Which is very useful to query internet naming servers.
1) Lets see how to retrieve the ip address from the URL ( eg. www.google.com )
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | $ nslookup www.google.com
Server: 218.186.2.16
Address: 218.186.2.16#53
Non-authoritative answer:
Name: www.google.com
Address: 173.194.38.147
Name: www.google.com
Address: 173.194.38.146
Name: www.google.com
Address: 173.194.38.145
Name: www.google.com
Address: 173.194.38.144
Name: www.google.com
Address: 173.194.38.148 |
If you want only the ip address, then you can awk the output of the nslookup output.
1 2 3 4 5 6 7 8 9 | $ nslookup www.google.com | awk '/Address/&&!/#/' Address: 173.194.38.176 Address: 173.194.38.179 Address: 173.194.38.180 Address: 173.194.38.178 Address: 173.194.38.177 $ nslookup www.facebook.com | awk '/Address/&&!/#/' Address: 66.220.149.94 |
If you type the above ip addresses, then you will be directed to corresponding website.
