tnsping would require the use of a name in the tnsnames.ora file as a parmeter.  I don't believe it takes an IP address.  If it does, that is not enough information, it also needs to know which port to contact.

Newer versions of tnsping will take an ip address and attempt to locate a listener.

With the posted output I'm pretty sure the 9.2 version didn't accept them but that was a long time ago.

I thought that it would take IP in newer versions.  But I ran across this piece of documentation:

http://docs.oracle.com/cd/E11882_01/network.112/e41945/connect.htm#NETAG378

It clearly states that it requires a net name.

Honestly I didn't try it with an IP.  I guess the documentation could be incomplete.  Also, note that it definitely states that different platforms have different interfaces, so it may work in one place but not another.

I managed to dig up the same documentation in a 9.2 release of the documentation.  It is almost word for word the same documentation, so either the utility is identical (which is possible), or the documentation hasn't been updated for newer features.

>>It clearly states that it requires a net name.

I tried it before I posted...

Part of my ipconfig:
Ethernet adapter Local Area Connection:
   IPv4 Address. . . . . . . . . . . : 192.168.1.10(Preferred)
   Subnet Mask . . . . . . . . . . . : 255.255.255.0

Interesting.  The documentation clearly doesn't support what the utility does.  A documentation bug I guess.
