actually I think it still is pretty useful...
In IPAM you are not able to alter most fields either (hostname I believe was and is possible) because they would be overwritten on the next scan anyhow, thats why you are able to edit the comment field or in IPAM create new editable custom fields.
In IPAM, if you disable the scanning for that one IP, you can edit all the fields.
But to get to your point... yes most of these free tools seem to be designed to only deliver limited usefulness, just enough to make you use it but not enough to productively use it as a main tool.
But what do you expect? Of course a company is not going to give away the best products with full functionality for free, they are meant to catch customers who crave for more.
I can only tell you that you are making a mistake if you dont even look at the other tools.
I haven't had a chance to try out ipmonitor but the Orion suite is quite nice, problems like everywhere else but it's difficult to find something that looks so nice, large functionality and still be able to customize everything... and all that in one interconnected suite!
Agreed. Unfortunately the tools that are not free are far too expensive for the non-professional user.
