I have located my proxy address, but don't know which part 
I have to enter into Options/proxy.

When I looked up my address, I got the following:

You came from: 81.104.163.174   (cpc2-duns3-3-0-
cust174.lutn.cable.ntl.com)
Remote address: 62.252.64.16  (cache5-lutn.server.ntli.net)
Remote host:             ditto.
Anyone please tell me what I should type into the box?Thanks.
Eric
