I’ve just changed the IP addresses of several of the PCs in my home network. They’re all still in the same range they were beforehand (192.168.1.0 network), but I just tweaked their addresses to re-order them sequentially the way I’d like.
From my PC where I have Glasswire installed, which is also on the same subnet, but whose IP I haven’t changed, I can successfully ping the other devices by hostname (which resolve to their new IPs) and by their new IP addresses directly.
But in GlassWire if I click ‘Scan’ on the Network tab, after the scan is complete I am still shown the old addresses. The MAC addresses for each network device are shown as being associated with the old IP addresses.
This comes as quite a surprise and a disappointment. It means I can’t trust the information that the Network tab is telling me. I really had thought that after manually initiating a scan, the information would be up-to-date. If I was relying on the information it’s giving me now, without knowing that many of the IP addresses had recently been changed, I’d be in trouble.
