Abstract

The shortage of IPv4 addresses is a reality and the adoption of IPv6 becomes necessary. IPv6 and IPv4 protocols are incompatible and have different operational issues, which makes the IPv6 implementation relatively difficult for many IPv4 network administrators. In order to help reducing this gap, this article presents a comparison between IPv4 and IPv6 related to a day-by-day campus network administration. It also presents the acquired experiences and lessons learned from a successful IPv6 implementation using the Dual-Stack technique to reduce barriers of the IPv6 adoption for small network campus.

Highlights

  • THE IPv4 protocol uses 32 bits for IP addresses and has become the standard protocol of Internet since the 80s because of its robustness, easy configuration and massive adoption by the hardware manufacturer

  • - Software/hardware information belonging to the legacy network infrastructure must be analyzed, looking for IPv6 support/documentation from their manufacturer

  • As verified in this work, the Windows XP (Service Pack 2 or 3) needs to operate with the Dual Stack technique to bypass problems with DNS and SMB services - A small testbed network infrastructure must be built in order to evaluate the real operation of critical services (DNS, Firewall, Routers, Proxy, enterprise software, mobile devices, printers, etc.) only with IPv6
