There are three types of Private Unicast IPv6 addresses (there are also various types of multicast addresses). There was a desire to avoid the problem seen with private V4 addresses that address conflicts were likely when a host needed to access multiple private networks at the same time or when two previously separate private networks needed to be integrated.

Nov 18, 2018 Implementing IPv6 In A Home Network - Tips & Pitfalls For local IP addressing, there is a construct called a Unique Local Address (ULA) that is a section of private IPv6 address space carved-out specifically for traffic on LANs (similar to the RFC1918 space in IPv4). To maintain a consistent IPv6 address for each host on the LAN, it will be necessary to generate an IPv6 ULA prefix and assign a How to configure IPv6 address in Windows

Feb 08, 2011 · Basic understanding of IPv6 addressing, and acquiring an IPv6 address block. Configuring Static IPv6 addresses on Windows 2008 R2 servers, Windows 7 workstations, and configuring DNS

For IPv6 addressing, each company should do subnetting on the assigned IPv6 address block, and only use addresses from within that block. As a result, that company uses addresses that are unique across the globe as well. The second IPv6 option uses unique local addresses, which work more like the IPv4 private addresses. In IP networking, a private network is a network that uses private IP address space. Both the IPv4 and the IPv6 specifications define private IP address ranges. These addresses are commonly used for local area networks in residential, office, and enterprise environments. Private network addresses are not allocated to any specific organization. Anyone may use these addresses without approval from regional or local Internet registries. Private IP address spaces were originally defined to assist in
