It still attempts IPv6 communications. It has to explicitly be told not to. Apt attempts IPv6 first, again unless told not to. I haven't found any other problems yet, as this is on a server and no web browsing occurs. Apt obviously uses http access, but once name resolution was fixed and it was told to use IPv4, there has been no trouble. I expect at some point that my ISP will open up IPv6 access, but it is currently giving no expected date. -- Joe
