search Search list for host-name lookup.
The search list is normally determined from the local domain name; by default, it contains only the local domain name. This
may be changed by listing the desired domain search path following the search keyword with spaces or tabs separating the
names. Resolver queries having fewer than ndots dots (default is 1) in them will be attempted using each component of the
search path in turn until a match is found. For environments with multiple subdomains please read options ndots:n below to
avoid man-in-the-middle attacks and unnecessary traffic for the root-dns-servers. Note that this process may be slow and will
generate a lot of network traffic if the servers for the listed domains are not local, and that queries will time out if no
server is available for one of the domains.
The search list is currently limited to six domains with a total of 256 characters.
大概看的差不多,但是哪位大哥能精辟的讲解一下呢? |
