Listener not starting after DNS and Gateway entries update

Hi,

Due to non-connectivity of SAP Router our unix/network team has changed the Public IP's Gateway and DNS entries on our Unix Server.

After that our SAP Instance Listener service is not starting due to which SAP is also down. Kindly let me know what can be done to resolve this. Ours is local installation

Below are the relevant entries:

Output of TNSPING:

    (HOST = ABCD) (PORT = 1527)...

    TNS-12545: Connect failed because target host or object does not exist

    first question will be can you ping host ABCD?, can you telnet ABCD on port 1527?

    If not then you know what the problem is...

    Issue was resolved as in listener.ora file, I commented entries for IPC protocol. After that listener started.
