Hmmz so what does the 'nott' in nott-grim-ubr-1.inet.ntl.com mean?
I should clarify I was referring to an IP hub, probably should have called it a POP site, rather than an HFC hubsite. You don't have any way of knowing what your HFC hubsite is as it doesn't even necessarily have a uBR in it.
However in the context of the OP question all is irrelevant so I'll put what you said down to attempted points scoring
