in reply to (code) Resolve list of DNS names

Check out this recent thread on validating IP addresses. It's not quite as simple as you might think.

    Thanks for the thread-link, mikeB.   8^)

    However, my infile sanity-check isn't intended to parse or untaint IP addresses.   If I ever do add support for IP address input (reverse-lookups), I'll likely look to CPAN for a module.   A quick search turned up these candidates: Net::IPAddr-Find, Net::IPv4Addr, Net::IP, and NetAddr::IP.

      Get the following error. What should i do? print (...) interpreted as function at ./resolve.pl line 112. syntax error at ./resolve.pl line 120, near "sub UNLINK " Can't use global @_ in "my" at ./resolve.pl line 121, near "= $_" syntax error at ./resolve.pl line 128, near "}" Execution of ./resolve.pl aborted due to compilation errors.
        Yes. The program runs now but now I get the following error. Error reading input file "resolve.in": No such file or directory. I created the file resolve.in in the home folder with resolve.pl and put a list of domains in it ie: google.com yahoo.com aol.com But still get the same error. My System Mac OSX 10.4.11 Net::DNS 0.65 Spreadsheet::WriteExcel 2.25 Perl 5.008006 Local OS darwin
        The new error it created after I put the resolve.in file was: Error reading input file "resolve.in":
        Whew! Finally got it to work. Now is there a way to make this multi-threaded? I'm a newbee so I have no idea how to accomplish this.
