Although site-local addresses were originally defined for use in networks that were not yet connected to the Internet, there has been work underway for several years to expand the use of site-local addresses to globally connected IPv6 networks and nodes. The use of site-local addresses on globally connected networks and nodes raises complex technical issues for many parts of the TCP/IP protocol suite. Many of these issues are caused by the fact that IPv6 sites are private address spaces, and site-local addresses are unreachable or ambiguous outside the borders of their originating site. Site-local addresses also add significant complexity at the IP layer and at other layers of the protocol stack. In addition, many of the benefits of site-local addressing can be achieved using mechanisms that are significantly less complex and that cause fewer problems than IPv6 site-local addressing. This document makes a recommendation to limit the use of site-local addresses to isolated, single-site networks, and offers suggestions for less complicated mechanisms to achieve many of the benefits currently attributed to IPv6 site-local addressing.}, }
