This document summarizes Agence Wallonne des Télécommunications (AWT)'s experience with IPv6 deployment from 2006 to present. AWT first obtained an IPv6 address block in 2006 and began offering external IPv6 services in 2008 using a separate VLAN. In 2009, AWT disseminated IPv6 to the public sector in a trial. By 2010, AWT had implemented dual stack services on its DMZ and LAN for users and guests. Currently, AWT offers dual stack services across its internal and external networks and continues migrating workstations to dual stack. The document outlines AWT's approach and lessons learned, emphasizing the importance of teamwork, IPv6 understanding, compatibility testing, and online resources
