This section contains links to the official standards that specify IPv6 and other parts of the Internet. If there is any disagreement between information on this site and the contents of these IETF standards, the IETF standards are correct. I have tried to make sure all the content I’ve written is in full compliance with these standards, as well as with observed behavior of actual networks, but some errors may creep in. Any such errors should be reported to me.
