Mostly because I am having ongoing connectivity issues, I did in fact have a phone conversion, at last, with some actually knowledgable person(s) at my ISP (Surewest aka Consolidated Communications), and among the many questions I asked, I did also ask if the old (ancient?) gateway address I had been using was still the current and proper one, and sure enough, no, the current proper one is now the .1 address within the /24 I happen to be located in. So I've changed that now. (I do thank you for the suggestion, but I had already planned to ask them if I was using the correct gateway address.) Oddly, even though I now have the defaultrouter address in my /etc/rc.conf file set to the .1 address, _now_ my traceroutes are showing the .2 address in this same /24 as the first hop. Oh well, I'm not going to worry about it. I have bigger fish to fry. (Specifically, my ISP now informs me that there are definite problems with either my ADSL2+ router, or my line, or both, and I will be working with them to correct those issues.)
