IPv6

IPv6 Enabled Servers

Most of the AAISP servers are IPv6 enabled, for example:

• POP3/IMAP Email servers
• Webmail servers
• Incoming SMTP Servers
• Outgoing SMTP Servers
• Backup email relay
• Customer facing DNS Servers
• Internet Facing DNS Servers
• Web server
• Control Pages
• Accounts system (Billing)
• NTP Time Server

These servers have been IPv6 enabled for many years, as have the desktop computers in the AAISP Offices.

Currently the VoIP services are IPv4 only.

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

Again, we have been providing IPv6 for customer connections (eg ADSL) for many years. either Tunnelled or Native.

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.

(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:[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.
