Anyone know if they use a proxy? it would appear in my trace route a proxy shows up (see below) but none of the usual signs of a proxy server.
the proxy is "ptb-proxy02.plus.net"
Tracing route to bbc.co.uk [212.58.253.67]

I expect the reverse dns entry for 212.159.0.106 is outdated:

Re: Plusnet proxy?

Hi
No its not a proxy.  Its an old DNS entry for an IP we have re-used as part of the DPI work that is going on.  They will all be cleaned up/updated as part of that work.

Re: Plusnet proxy?

The hint being the ptb part of the name.  That's technology building!  We haven't been in there for about 5 years! Cheesy
