IPv4

Internet Protocol version 6 (IPv6) is the “new” Internet addressing protocol created by the Internet Engineering Task Force (IETF) to deal with the exhaustion of the current IPv4 address space. In Part One of this article I gave you some background in IPv6 and documented your path from IPv6 Certified Newb to Enthusiast. In Part Two we’ll finish the Hurricane Electric IPv6 Certification process and you’ll be end up being a Sage. Administrator The IPv6 Administrator not only runs a valid IPv6 addressed web site, but also a valid IPv6 addressed mail server. For this certification, you’re going to have to configure a mail server that resolves via IPv6 DNS, can be connected to over IPv6, and...
