Hi Folks,

I regularly ssh into my office computer when working from home. I've
set iptables to require an on-campus or NCSU VPN source IP address.
However, I'd like to restrict incoming ssh connections to a RoadRunner
residential subnet so I can avoid having to be routed through the VPN.

MY QUESTION: How, if at all, can I determine a RoadRunner residential
subnet mask encompassing my residence (and not all RR residential across
the nation, of course)? Is this information available? Anyone else
tried something like this before?

Thanks,
Daniel
