while is not setting $_ for you. in

while (<PINGALLIP>) {
   if (/is alive/) {
      chomp;
      print ALIVEIP $_;
   }
}

Try this instead:
/is alive/ and print ALIVEIP for <PINGALLIP>;

If the match is true then print $_ for all lines. I omitted chomp since the record delimiters will probably be handy in the file.
