In this case, there is a wrong configuration of the local router/dns server.
The returned IP 18.104.22.168 is an intenet address. The local physiical network has a configured DNS on 192.168.1.254, this address is reserved for special use on the Cisco security agent. The local router device must be reconfigured to not be a DNS or not use 192.168.1.254.
Looking at the Hub settings sure enough 192.168.1.254 is the Hub IP Gateway Address.
There are some instructions here on BT site on how to change the settings
But, if I follow these and change:
Will this cause any problems?
Thanks in advance for your help

OK... no one knows. Fair enough.
Thought I would answer myself in case it helps anyone using the search facility in the future.
I found that in fact you can reset the hub to a different preset range of IP addresses. 172.16.0.nn
This worked fine, and does NOT reboot the hub in case anyone is concerned about that.
Note you may need to renew the DHCP lease on the attached PCs... this is simply opening a command prompt:
type "ipconfig" (no ") if that shows an IP address in the old range then type
ipconfig /release - should now have zeros
ipconfig /renew - should now have an IP address in new range
One of the techies that did not answer this may say you do not need the "release" first. But I was not sure so did both.
This also fixed the contention with the VPN's Cisco Security Agent

Sorry nobody got back to you about this - thanks for giving us an answer anyway! I personally have the default gateway set to 192.168.1.3 as I have two other routers I use for access points on .1 and .2 - keeps things neat in my head (I also have DHCP switched off).
