    Hi PE,
    how about resolving IP addresses, whois, receiving data packets to your system, tracert, etc.?
    It only doesn't need to act as a server, but connect to internet yes, is necessary.
    You might like to add the PE process to the socket spy and look at it's traffic.

    Hi there PE, thanks for your question - it's a reasonable one, and one we're asked regularly.

    At the end of the day, Port Explorer doesn't need any Internet access at all - it will work just fine without it, but naturally if you want to use network-related utilities that are built-in, such as Resolve, Traceroute, Whois, etc etc, then those utilities will naturally need Internet access. Remember, just resolving an IP address requires Internet access.

    From the Troubleshooting | Frequently Asked Questions section of the helpfile (pehelp.chm):

    Do I need to allow Port Explorer access through my personal firewall?
    You don't have to, but it is recommended. If you block Port Explorer with your firewall you won't be able to do such things as resolve/traceroute/ping addresses, or use utilities such as the Whois client, but these would be the only restrictions.

    I might just add that Port Explorer always RESOLVE's addresses in the main table even when resolving of addresses is turned off. This is so when its reenabled again all the addresses will be resolved and there won't be any time taken to resolve them all.

    Sometimes windows takes DNS requests using Port Explorer and sometimes it goes through SVCHOST (depending on whether your on WinNT kernel or Win9x). Port Explorer doesn't NEED any internet connection as has been said, just you will lose the ability to use some features if you don't.
