The WINS resource record is used for forward lookups. When a resolver sends a query to the DNS server, requesting the corresponding A resource record, and the DNS server does not find the name in the forward lookup zone, it uses the WINS record to locate a WINS server that might be authoritative for the leftmost label of the FQDN. If present, the WINS record only applies for the topmost level within a zone and not for subdomains used in the zone. A WINS resource record has the following syntax:
<domain> <class> WINS [<TTL>] <Local> <LookupTimeout> <CacheTimeout> <IP address of WINS server>
where the placeholders have the following meanings:
domain. Domain name where the WINS record is found. It is always @.
class. Class is always IN for WINS records.
TTL. Time that a WINS record can be cached before it must be discarded.
Local. Specifies whether the record must be included in zone replication.
LookupTimeout. Time in seconds that a DNS server that uses WINS lookup waits before it gives up.
CacheTimeout. Time in seconds that a DNS server that uses WINS lookup can cache the response from the WINS server.
WINSServers. List of IP addresses of the WINS servers to be used.
The following is an example of a WINS resource record:
@ IN WINS LOCAL 5 3600 172.16.72.3
The
<domain> <class> WINSR [<TTL>] <Local> <LookupTimeout> <CacheTimeout> <NameResultDomain>
where the placeholders have the following meanings:
domain. Domain name where the WINS record is found. It is always @.
class. Class the field is IN.
TTL. Time that a WINS record can be cached before it must be discarded.
Local. Specifies whether the record must be included into zone replication.
LookupTimeout. Time in seconds that a DNS server that uses WINS lookup waits before it gives up.
CacheTimeout. Time in seconds that a DNS server that uses WINS lookup can cache the response from the WINS server.
NameResultDomain. Domain to append to returned NetBIOS names.
The following is an example of a
@ IN WINS-R LOCAL 5 3600 reskit.com.
