8 Saying Y here will include support for the DNS Resolver key type
9 which can be used to make upcalls to perform DNS lookups in
10 userspace.
11
12 DNS Resolver is used to query DNS server for information. Examples
13 being resolving a UNC hostname element to an IP address for CIFS or
14 performing a DNS query for AFSDB records so that AFS can locate a
15 cell's volume location database servers.
16
17 DNS Resolver is used by the CIFS and AFS modules, and would support
18 samba4 later. DNS Resolver is supported by the userspace upcall
19 helper "/sbin/dns.resolver" via /etc/request-key.conf.
20
21 See <file:Documentation/networking/dns_resolver.txt> for further
22 information.

24 To compile this as a module, choose M here: the module will be called
25 dnsresolver.

27 If unsure, say N.
