Understanding and deploying IPv6

Home > Products and services > Training > Understanding and deploying IPv6

The old version of the Internet Protocol, IPv4, has been such a success that we are now faced with a shortage of available addresses. This has the effect of heavily penalising new entrants as well as other players who no longer have enough IPv4 addresses. Maintaining IPv4 is also proving more and more costly for businesses.

It is therefore advisable to migrate to the new version of the protocol (IPv6) in order to manage a scalable and extensible pool of IP addresses.

Description and aims of the training course

This training course will enable you to:

  • Master the concepts and issues of IPv6
  • Understand the key factors for a successful transition to IPv6
  • Organise the deployment of IPv6 within your company

1 day

Target audience
System and network administrators, CIOs and deputy CIOs


  • Experience in one of the following business lines
  • Familiarity with the TCP/IPv4 protocol suite (the reminder of certain functional aspects of IPv4 will be solely for the purpose of comparison as a teaching aid)

Stéphane Bortzmeyer, Afnic IPv6 expert
