- ;
- ; Lookup file for place.dom domain.
- ;
- ; Note that all domain names given in this file, which are not
- ; terminated by a "." and hence fully qualified domain names (FQDN),
- ; are implicitly appended with "place.dom."
- ;
- ; Examples:
- ; "host" => host.place.dom.
- ; "host2.subdomain" => host2.subdomain.place.dom.
- ;
- ; If a name outside of "place.dom." is required, then it must be
- ; explicitly terminated with a dot, to indicate that it is a
- ; FQDN.
- ;
- ; Example:
- ; "host.mycompany.com." => host.mycompany.com.
- ;
-
- ;
- ; START OF AUTHORITY
- ;
- ; The first record in any database file should be a "Start of Authority"
- ; (SOA) record. The fields of this record are:
- ;
- ; IN SOA <source host> <contact email> <serial number> <refresh time>
- ; <retry time> <expiration time> <minimum time to live>
- ;
- ; <source host> is the host on which this file was created.
- ;
- ; <contact email> is the email address if the person responsible
- ; for this domain's database file. Instead of
- ; writing an '@' in the email name, write a '.'
- ;
- ; <serial number> The "version number" of this database file.
- ; Increase this number each time you edit a
- ; database file.
- ;
- ; <refresh time> A time, in seconds, that a secondary server
- ; will wait between checks to your server, when
- ; deciding if it is time to download a new copy
- ; of this domain's data.
- ;
- ; <retry time> A time, in seconds, that a secondary server
- ; will wait before retrying a failed zone download.
- ;
- ; <expire time> A time, in seconds, that a secondary server will
- ; keep trying to download a zone. After this time
- ; limit expires, the old zone information will be
- ; discarded.
- ;
- ; In order for a resource record to span a line in a database file,
- ; parentheses must enclose the line breaks, as in the following
- ; example.
- ;
- ;
- ; YOU SHOULD CHANGE:
- ; - "machine.place.dom." to the name of your name server.
- ; - "postmaster.machine.place.dom." to your email name.
- ;
-
- @ IN SOA nameserver.place.dom. postmaster.nameserver.place.dom. (
- 1 ; serial number
- 36000 ; refresh [1h]
- 600 ; retry [10m]
- 86400 ; expire [1d]
- 3600 ) ; min TTL [1h]
-
- ;
- ; NAME SERVERS
- ;
- ; The following entries list the name servers for this domain.
- ; This information allows other name servers to lookup names in
- ; your domain.
- ;
- ; YOU SHOULD CHANGE:
- ; - The names of the DNS servers.
- ; - The addresses of the DNS servers.
-
- @ IN NS nameserver.place.dom.
- @ IN NS nameserver2.place.dom.
-
- nameserver IN A 192.5.29.7
- nameserver2 IN A 192.5.29.8

- ; WINS LOOKUP
- ;
- ; The WINS RR is specific to WindowsNT and may be attached ONLY
- ; to the zone root.
- ;
- ; Presence of a WINS record at the zone root instructs the name server
- ; to use WINS to lookup any requests for A (address) records for names
- ; which are DIRECT children of zone root, and which do NOT have A
- ; records in the zone file.
- ;
- ; Examples:
- ;
- ; 1) A query for host.place.dom.
- ; "host.place.dom." has A records below, so DNS server responds
- ; with A records without WINS lookup.
- ;
- ; 2) A query for website.place.dom.
- ; "website.place.dom." is in the place.dom zone, but has no A records
- ; within this zone file. DNS queries WINS for a workstation
- ; name "website", gets a response or name error back from WINS,
- ; caches it and responds to the client.
- ;
- ; 3) A query for website.microsoft.com.place.dom.
- ; "website.microsoft.com.place.dom." is in the place.dom zone,
- ; and has no A records within this zone file. However, it is
- ; not an DIRECT child of the "place.dom." zone root, so the MS
- ; DNS does NOT query WINS and responds with a name error.
- ;
- ;
- ; WINS and sub-domains:
- ;
- ; Note: the MS DNS avoids going to WINS for queries like #3, because
- ; resolvers will append local domain names, and WINS only "knows"
- ; about the hostname. Hence if WINS lookup was done, WINS would
- ; respond with the address for the matching hostname it had, when
- ; the desired hostname was for at another site (website.microsoft.com
- ; in the example above).
- ;
- ; If your site has multi-level domain names that you wish to resolve
- ; through WINS, you must break the subdomains into separate zones.
- ;
- ; Example:
- ; You have several domains containing hostnames
- ; - xxx.place.dom
- ; - yyy.finace.place.dom
- ; - zzz.production.place.dom
- ; But each domain has some names registered in WINS.
- ;
- ; To use WINS resolution, break up place.dom into separate zones:
- ; - place.dom
- ; - finace.place.dom
- ; - production.place.dom
- ; each with its own WINS record at the zone root.
- ;
- ;
- ; WINS and zone transfer:
- ;
- ; The MS DNS server, will configure WINS information as a resource
- ; record to allow it to be transferred to MS DNS secondary servers.
- ;
- ; If you have MS DNS secondaries, and want them to use exactly the
- ; same WINS servers as the primary server, then omit the LOCAL flag
- ; in the WINS record.
- ;
- ; If you have UNIX secondaries, or MS secondaries using different
- ; WINS information, then use the "LOCAL" flag after the "WINS"
- ; flag and the WINS information will NOT be considered part of the
- ; zone's resource records and will NOT be sent in the zone transfer.
- ;
- ;
- ; YOU SHOULD CHANGE:
- ; - Change the server addresses to the address(es) of the WINS
- ; servers for the WINS clients in this zone.
- ; - Uncomment the line without the LOCAL flag, if WINS information
- ; should be transferred to MS DNS secondaries.
- ; - Uncomment the line with LOCAL flag, if WINS information should
- ; not be transferred as part of the zone data.
- ; OR
- ; - Leave this line commented out, if WINS lookup not desired.
- ;
-
- ;@ IN WINS 192.5.29.2 192.5.29.3
- ;@ IN WINS LOCAL 192.5.29.2 192.5.29.3
-
-
- ;
- ; LOCAL HOST
- ;
- ; Each of your domain files should contain an entry for the name
- ; "localhost". Be careful not to type a trailing dot in this entry
- ; unlike the use of localhost in the reverse-lookup files.
- ;
- ; This allows lookups for "localhost.place.dom." to return 127.0.0.1.
- ; As unusual as this may seem, some vendors' name resolvers depend
- ; upon it.
- ;
- ; YOU SHOULD CHANGE:
- ; nothing
-
- localhost IN A 127.0.0.1
-
-
- ;
- ; E-MAIL SERVERS
- ;
- ; The following entries list the email servers for this domain.
- ; The numeric value is a "preference value," with 1 being most
- ; preferred. Therefore, in the example given, mail will only be
- ; delivered to testmail2.place.dom. if testmail1.place.dom.
- ; is down or not receiving mail.
- ;
- ; By using these records, mail addressed to user@place.dom. is
- ; delivered to user@mailserver1.place.dom.
- ;
- ; YOU SHOULD CHANGE:
- ; - The names of the mail servers.
- ; - The addresses of the mail servers.
-
- @ IN MX 10 mailserver1
- @ IN MX 15 mailserver2
-
- mailserver1 IN A 192.5.29.17
- mailserver2 IN A 192.5.29.18
-
-
- ;
- ; OTHER HOSTS
- ;
- ; The following 'A' records designate IP numbers for the named
- ; hosts.
- ;
- ; The 'MX' records designate a mail server and priority for a
- ; domain name.
- ;
- ; Unfortunately, there is no suitable wild-card syntax to allow
- ; you to enter these records once only.
- ;
- ; YOU SHOULD CHANGE:
- ; - The names of the hosts listed.
- ; - The IP addresses given.
- ; - The mail exchange information for non-default mail servers.
- ;
-
- WINSsrv1 IN A 192.5.29.2

-
- ;
- ; CNAME RECORDS
- ;
- ; The following records are sometimes called "aliases" but are
- ; technically referred to as "Canonical Names (CNAME)" entries.
- ; These records allow you to use more than one name to point to
- ; a single host.
- ;
- ; For example, the entries below mean that:
- ;
- ; ftp.place.dom. is really host.place.dom.
- ; www.place.dom. is reallt other-host.place.dom.
- ;
- ; By using CNAME records, you avoid typing duplicate information
- ; in your database files.
- ;
- ; YOU SHOULD CHANGE:
- ; - The names of the hosts given.
- ;
-
- ftp IN CNAME host
- www IN CNAME other-host
