Well, as you might remember, having migrated all of the self-hosted websites to the Arizona host from the Rugby infrastructure (so there are no domains pointing to the static IP address here), I closed port 80 on the router.
That was a week ago.
This evening, just for a laugh, I opened port 80 on the router. You have to remember that there are no domains hosted in Rugby, so there can be nothing pointing to a domain inside the router.
As soon as I saved the new #open port 80# config on the router, the port 80 calls started appearing:

So, it’s safe to assume that all of these (and probably most of the historic) port 80 calls are routing to the static IP address configured inside the router, not to any domain name.
Interesting.
