NTOP - Never really gets internal host names correct.

[steve.hills]

Hello,

we use NTOP quite frequently, to see who is currently hogging up all of our bandwidth. The problem is that while the Throughput screen happily shows the IP address of the host, the hostname it shows is usually incorrect. as our users all use DHCP, I suspect theres a problem with the DNS name changing and this being out of step with NTOP / PFSense, but for the life of me I cant see where to fix this.

Suggestions?
