How to get more host names resolved   24 January 2019, 23:19

Hello,

We have purchased the Port Mapper license, and now have the problem that we only get very few client host names resolved to the IP addresses. Is there any way to improve this? This feature was the main reason we bought the product, and it wasn't predictable with the trial version because of the restriction with only 10 devices in the trial.

This is a screenshot. Only the ones highlighted in yellow have a resolved host name:

Thanks for your support.
Best regards

Please try the latest preliminary build of the Port Mapper: in addition to DNS names it now also attempts to resolve NetBIOS names.

If some names still don't show up, it is most likely because those devices either don't have names or don't reveal them via standard protocols.

To check, you can open a command prompt and type an IP that has a resolved name, for example:
tracert 192.168.17.248
This should return the same name as displayed in the Port Mapper.

Then try an IP with no resolved name, for example:
tracert 192.168.17.247
If no name is printed, it is due to one of the reasons mentioned above and unfortunately there isn't much that can be done about it. You may have to configure these device addresses manually in your DNS server(s) to enable reverse name resolution.
