What happens if you put "jpsoft.comx.zz" in your browser's location box?
It wouldn't surprise me if your ISP were doing "DNS Redirection" ... in which DNS returns a "special" IP when you attempt to look up an unknown host. That screws up NSLOOKUP, and if your in a browser, usually results in your being taken to a site that tries to be helpful (mostly with ads).
I had RoadRunner turn off DNS Redirection years ago. But, because of this thread I discovered it was turned on again (no doubt because I bought my own cable modem a while back). It's turned off again after an unnecessary hour on the phone with RoadRunner. It's a simple task (DOCSIS modem setting). Tier 1/2 techs can do it but they didn't know about it (probably typical). The tier 3 tech I finally got knew about it but took 15 minutes figuring out which tool he needed to use to change it.
