IPv6 Peering

LONAP members can exchange IPv4 and IPv6 traffic on their LONAP ports.

IPv4 and IPv6 peering take place on the same LONAP peering VLAN. If you are adding IPv6 to a port for the first time, please contact support so we can update your details.

Please ensure that you have disabled both IPv6 Router Solicitation and Router Advertisement on your port which faces LONAP. You must only use BGP for prefix exchange on LONAP.

Once you have configured your IPv6 peering address, please contact LONAP Support, as you should then turn up an IPv6 collector session. Our Route Servers also support IPv6.

Members can calculate their own peering addresses, as LONAP use a schema to assign v6 peering addresses. 2001:7f8:17::ASNHEX:RTR/64, where ASNHEX is your AS Number represented in hexadecimal, and RTR is a counter (your first router is :1, your second is :2, etc).

For example: AS 8330 in hex is 208A. The IPv6 address would be: 2001:7f8:17::208a:RTR/64

Members with 32 bit AS numbers should use the next nibble to the left in the IPv6 address, for example, AS 223456 in hex is 368E0. The IPv6 address would be: 2001:7f8:17::3:68e0:RTR/64

You can use the calculator below to determine the IPv6 address you should use. You are free to assign :1 and :2 to your connections as you see fit, but please drop a line to support so we can update our records.

Please enter your ASN to calculate your IPv6 addresses.


Prior to 2008, LONAP members had to take a multi-VLAN port, or multiple ports, in order to peer IPv4 and IPv6, as VLAN 4 was only used for IPv4 peering, and all IPv6 peering occurred with VLAN 6.

In 2008, LONAP consulted members on running a dual-stack peering VLAN, and members signalled strong preference for this. All public peering now takes place in a single VLAN.
