| SSAC Advisory on DNS "Search List" Processing (R-1) | SAC064 | CLOSED |
Description:
The SSAC invites all ICANN Supporting Organizations and Advisory Committees, the IETF, and the DNS operations community to consider the following proposed behavior for search list processing and comment on its correctness, completeness, utility and feasibility.
a. Administrators (including DHCP server administrators) should configure the search list explicitly, and must not rely on or use implicit search lists; Where DNS parameters such as the domain search list have been manually configured, these parameters should not be overridden by DHCP.
b. When a user enters a single label name, that name may be subject to search list processing if a search list is specified, but must never be queried in the DNS in its original single-label form.
c. When a user queries a hostname that contain two or more labels separated by dots, such as www.server, applications and resolvers must query the DNS directly. Search lists must not be applied even if such names do not resolve to an address (A/AAAA). Therefore www.server is always a FQDN.
