I remember the anxiety generated over the lack of any new IPV4 addresses a year or so ago. All IPV4 addresses had been allocated and users were advised to check to see if their OS, routers and ISPs were IPV6 ready. I did the test too and found that the OS was ready, but that my ISP was not. ManyTech articles indicated that many routers were not firmware upgradeable to IPV6. Trouble would ensue. Has anybody had any problems with IPV6 websites loading slowly (with IPV4)? Has anybody had any bad experiences with their ISP over support for IPV6? Has anybody had a router problem regarding IPV6?
