![]() ![]() My not yet provide IPv6 server addresses with their service.įor what it's worth, I don't have any problems with devices connecting and using IPv6 addresses and the AirPort Extreme passes all the checks on sites like When I use an AirPort Extreme, devices on the network here do receive an IPv6 server number, but that number is the IPv6 LAN address of the AirPort Extreme, which means that devices are using the same IPv6 servers that the AirPort Extreme is using, which happen to be the Google IPv6 servers at this time. Unfortunately, nothing has changed in regard to IPv6 on the AirPort Extreme since it was introduced. Not much was known about IPv6 at that time, but Apple included some preliminary settings for the router. ![]() Keep in mind that the product, which was introduced in early 2013, was likely developed during the 2011-2012 timeframe. IPv6 is of a bare bones design in the AirPort Extreme if you are asking about the most recent "tall" or "tower" shaped version of the product. Unfortunately, without a traffic data dump, you will not be able to tell which method is being advertised by the Extreme. Going back to those fields: M = Managed address configuration & O = Other configuration, where: Instead the server will just provide the other configuration information, i.e., DNS, for example. Stateless DHCPv6 - With this method, the DHCPv6 server does not maintain any IPv6 information about the IPv6 clients.(I believe this is the method used when you enable the "Enable IPv6 Connection Sharing" option in the AirPort Utility.) Stateful DHCPv6 - With this method, the IPv6 client obtains its IPv6 address and configuration parameters from a DHCPv6 server.Stateless Address AutoConfiguration (SLAAC) - With this method, the IPv6 client to automatically self-assign itself a unique IP address after it learns what the local router's IPv6 prefix is.Depending on how they are set is how the router is offering the client its IPv6 addresses.Īn IPv6 client can obtain its IPv6 addresses in only one of three ways: Those fields are "Managed address configuration" and "Other configuration." Each of these fields can contain either a 0 or a 1. Ok, with that all said, the key is two fields in the Router Advertisement packet. This process is similar to that of ARP for IPv4. If all goes well, the Extreme will respond to that message with an ICMPv6 Router Advertisement message. In this case that would be your AirPort Extreme base station. If no duplicate addresses exist, then the client will send an ICMPv6 Router Solicitation message to discover any local routers. A local router will then send an ICMPv6 Neighbor Advertisement message in response to the client. To add a bit to what both Bob and LaPastenague have already provided you, an IPv6 client will attempt to obtain the appropriate IPv6 addresses by first sending a ICMPv6 Neighbor Solicitation to verify there are no duplicate IPv6 addresses. ![]()
