DNS Standards

Although the core DNS standards (as set forth in RFCs 1034 and 1035) have been well-established since their acceptance as standards in 1987, numerous revisions to DNS have been made in the intervening years. These revisions have been brought about by additional RFCs and Internet drafts, which are independently authored and submitted to the IETF for further circulation and review before being accepted as standards throughout the Internet.

Table 5.8 lists the accepted and proposed RFC standards that Windows 2000 supports.
