Don't take chances on IPv6 — start your preparations now!

By now, many of you have already begun preparing for your migration to IPv6. If you haven’t, I don’t want to scare you, but you need to start planning ASAP. I’ve said it before –– you will be left behind unless you migrate to the feature-rich, secure, and better-resourced world of IPv6.

You may have already read some of the IPv6 literature on the IETF website, followed the progress of industry leaders like Comcast, or started investigating options such as dual-stack deployment. At first, migration can seem complex, and even overwhelming. Don’t let this put you off. Creating a transition plan now will put you on the right track to enjoy more resources, better routing infrastructure, and a sustainable future.

The checklist below has been taken from our free IPv6 eBook Series. It outlines what you’ll need to do to prepare your network for the transition. This step-by-step audit covers the basic preparations required for IPv6 migration. Good luck!

Migration Checklist

  • Perform network audit of care switching and routing for IPv6 support
  • Plan IPv6 network topology and implement an IPAM solution capable of IPv4/IPv6 management integrated with DNS
  • Implement IPv6 peering with other providers
  • Perform network audit for subscribers using an IPv6 tunnel broker
  • Implement local IPv6 tunnel broker for clients. This includes testing a subdomain for AAAA records to start and providing maintenance window implementation of combined IPv4 and IPv6 A/AAAA records per zone
  • Perform network audit of access network
  • Determine the scope of clients affected
    • Cable and carrier xDSL operators will need to inventory IPv6-capable modems
    • IPoE network operators will require the IP DSLAM to be DHCPv6-capable
    • Carrier xDSL operators will need to test PPPoE client software for dual-stack support and check client support against supported client operating systems
  • Enhance DHCP systems with the following:
  • DHCPv6 support
  • DHCPv6 prefix delegation support
  • Dynamic DNS AAAA update support
  • Test application servers for transport over IPv6
    • Web servers (Apache)
    • Email servers
    • TFTP (Cable modem binary file downloads over IPv6)
    • SNMP
    • IPDR (Support of IPv6 data in IPDR requires DOCSIS 3.0)
