Using one grep operation instead of two?

Is there an efficient way to use grep in the following command that I am running, since I want to use only Perl's grep?

@found = grep { !/$IP/ } `$SSH $IPs[0] netstat -Aan | /bin/grep 1010`;

Basically, I am connecting to a fileserver, executing netstat command and grep IP addresses containing 1010. Then on this output I need to use grep to find a specific IP address. Can this be done somehow using only one Perl command?

Sure, you can do this:

@found = grep { /1010/ && !/$IP/ } `$SSH $IPs[0] netstat -Aan`;

The condition you use in grep can be not just an arbitrary expression, but even a full block of code if need be.
