We are provided with LAN inside our hostel, ip address starts from 172.... But few of days ago we start getting ip address of something like 192.... and internet stops working. We are told to fill static ip in setting( by seniors) in order to use internet. We did it ,internet starts working but i don't know why after that i am not able to ping anything like wheneer i type ping 22.214.171.124 it goes into loop, there is a server inside our college with address glug.nith.ac.in whenever i try to ping that with the given name like ping glug.nith.ac.in it says
ping: glug.nith.ac.in: Name or service not known
whenever i try to ping that server with its ip address like 172...__ it again goes into loop. SSH too not working. Why so ? And what's going arround with network in layman term?
