On June 8th 2011, SupraNet joined Facebook, Google and many others by participating in World IPv6 Day. IPv6 DNS records (AAAA) were enabled for our E-Mail, DNS, and webhosting. We had no issues and left all IPv6 services enabled.

We will also be participating in World IPv6 Launch Day which occurs on June 6th, 2012.

You can test your IPv6 readiness by visiting these sites:

IPv6 specific versions of some popular sites (these will only work if you have IPv6)

If you are interested in receiving an IPv6 allocation or enabling IPv6 on your website, please contact support@supranet.net. Information on how to configure your devices to utilize IPv6 can be found later on this page.


Allocations are available to SupraNet customers in sizes of /56. This contains 256 /64's, each which have 2^64 (18,446,744,073,709,551,616 or 18 Quintillion) usable addresses which will allow for autoconfiguration of hosts on a network (similar to DHCP).

To use IPv6 your network equipment (such as firewall or router) must support it. All modern operating systems such as Windows, OSX, Linux, FreeBSD support IPv6.

Please contact support@supranet.net for an IPv6 allocation.


SupraNet has two types of DNS servers: private/recursive servers for our connectivity customers, and our public/authoritative servers for domain name hosting. If you are configuring a system to do DNS queries, use the private DNS servers. If you are registering a domain and want SupraNet to host DNS, use the public servers.

SupraNet's private DNS servers will not answer queries from systems outside our network.

Private DNS Servers:

  • 2607:F4E0:100:111::10
  • 2607:F4E0:100:111::19

Public DNS Servers:

  • dns1.supranet.net (2607:F4E0:100:111::11)
  • dns2.supranet.net (2607:F4E0:400:111::18)
  • dns3.supranet.net (2607:f740:b::f5e)


Cisco IOS

!! Enable IPv6 
ipv6 unicast-routing

!! Add IPv6 Address to an interface 
interface FastEthernet0/0

  • Sample of a static IP and default route
interfaces {
    ge-0/0/0 {
        unit 0 {
            family inet6 {              
                address 2607:F4E0:xxxx:xxxx::2/64;
    rib inet6.0 {
        static {
            route 0::/0 next-hop 2607:F4E0:xxxx:xxxx::1


  • Modify /etc/rc.conf. IPv6 should be working upon next boot:

  • To bring it up live without a reboot you must do a little more work. The last four steps are to get the Link Local (fe80) addresses active:
ifconfig em0 inet6 2607:f4e0:xxxx:xxxx::2/64
route add -inet6 default 2607:f4e0:xxxx:xxxx::1
sysctl net.inet6.ip6.auto_linklocal=1
ifconfig em0 down up
/etc/rc.d/network_ipv6 start
rtsol em0


  • Modify /etc/hostname.xxx and add the address to a new line:
inet6 2607:F4E0:xxxx:xxxx::2 64

  • Set a default gateway by adding a new line to /etc/mygate:

Linux (Debian)

Debian should assign an IPv6 address automatically if your default gateway is configured with auto configuration.

  • To assign a static IP, modify /etc/network/interfaces
iface eth0 inet6 static
	address 2607:F4E0:xxxx:xxxx::2
	netmask 64
	gateway 2607:F4E0:xxxx:xxxx::1

  • To bring it up live:
ifconfig eth0 add 2607:F4E0:xxxx:xxxx::2/64
ip -6 route del ::/0
ip -6 route add ::/0 via 2607:f4e0:xxxx:xxxx::1

Windows XP

Windows XP must have the IPv6 Protocol added

  • Open Control Panel
  • Network Connections
  • Get the properties of your NIC (Local Area Connection if wired)
  • Click Install
  • Choose Protocol and Add
  • Choose Microsoft as the manufacturer, Microsoft TCP/IP verison 6, click OK

Windows 7

Windows 7 should assign an IPv6 address automatically if your default gateway is configured with auto configuration.
