At a house with a basic setup. Router and wifi; multiple PCs connected. All computers on the network are able to use the internet without problems. None of the computers can get to a specific site, http://www.ebsconsultants.net
(resolves to 220.127.116.11). CAN see this website from multiple other locations on those same computers. There are no known RBLs on the site.
It's an ATT U-verse router (don't have the model number).
-Basic settings on the router.
-Firewall is in default mode.
-Reset the router - didn't help.
-Neither Mac and PCs can't reach the domain.
-Tried using OpenDNS on the computer
-Can even ping to 18.104.22.168 and 104 (hence to the same web/mail host), but not 103.
-Able to surf to anything else attempted, except this website.
Why is this one IP and domain causing a problem?
What else to try?
