IPv6 Enabled Servers
Most of the AAISP servers and services are IPv6 enabled as are the desktop computers in the AAISP Offices.
IPv6 Only
Here is our page about running an IPv6 only network: IPv6 Only
IPv6 Routers
We have a wiki page about IPv6 Routers IPv6 Routers
IPv6 for Customer Connections
Pages with IPv6 information on our main website:
- General IPv6 information
- IPv4 depletion plans
- NAT64 gateway (Mapping IPv6 traffic so you can get to IPv4 servers on the Internet.
See the IPv6 Configuration page for more details on hardware and configuration.
IPv6 on AAISP Broadband
This is how we route and assign IPv6 on DSL connections.
Customers are allocated a /48 block of addresses - this is usually per customer, and so a customer with multiple circuits or sites will have a /64 allocated from the larger /48 block. A /48 contains 65536 /64's and a /64 subnet is 18 million trillion addresses.
(Here, CPE refers to the router belonging to the customer which is being used at their end of the broadband line.)
When the CPE logs in and negotiates PPP we use IPV6CP to assign an IPv6 'WAN' address. This address is a single IPv6 address in the form of:
2001:8b0:1111:1111:0:ffff:[your IPv4 WAN in HEX]
At this point we will also be routing any IPv6 blocks to this WAN address. Usually a line will have at least one /64 block.
We also respond to DHCPv6 Prefix Delegation (PD) from the CPE and we'll tell the CPE one of the /64 Blocks. -this may be requested multiple times by the CPE.
The CPE will also assign itself a Link Local address in the form of FE80::, and will be based on the MAC address of the interface.
| Subnet | Addresses | |
|---|---|---|
| /48 | 18,446,744,073,709,551,616 | 18 million trillion |
| /64 | 65,536 lots of /48's |
Example Logs
PPP logs can be viewed from the control pages, it's the LNS Log button. Example:
