I attempted to use normal channels today at AT&T (enduser support) to address a reachability issue with AT&T Wireless to http://jimtest.delong.com. This left AT&T's enduser support utterly befuddled. Sadly, this is still the company that famously claimed ""We don't support reaching web sites over IP". Since I'm paying for the entire Internet, and not half of it, and enduser support is too ignorant to understand the problem, I'm wondering if someone here can tell me when AT&T Wireless intends to fix their LTE network since ARIN is out of IPv4 address space. Shame on you AT&T Wireless. Both T-Mobile and Verizon support IPv6. Andrew
