  2. MysqlBind - Wikipedia

    en.wikipedia.org/wiki/MysqlBind

    The unxsBind used SQL server is only needed to be operational for administration and deployment of new zones, new resource records, resource records changes and zone SOA changes. This non-reliance on a live SQL database has been a major point for reliable deployment of large scale DNS services.

  3. List of DNS record types - Wikipedia

    en.wikipedia.org/wiki/List_of_DNS_record_types

    Returns all records of all types known to the name server. If the name server does not have any information on the name, the request will be forwarded on. The records returned may not be complete. For example, if there is both an A and an MX for a name, but the name server has only the A record cached, only the A record will be returned.

  4. Domain Name System Security Extensions - Wikipedia

    en.wikipedia.org/wiki/Domain_Name_System...

    DNS resolvers use NSEC records to verify the non-existence of a record name and type as part of DNSSEC validation. NSEC3 (next secure record version 3) Contains links to the next record name in the zone (in hashed name sorting order) and lists the record types that exist for the name covered by the hash value in the first label of the NSEC3 ...

  5. DNS management software - Wikipedia

    en.wikipedia.org/wiki/DNS_management_software

    Tinydns quickly became the second most popular DNS server and a number of DNS managers were released for it, including: VegaDNS, SuaveDNS, and NicTool. In 2005, PowerDNS was released. One of its features was the ability to serve DNS data directly out of the SQL database, bypassing the export step entirely.

  6. Wildcard DNS record - Wikipedia

    en.wikipedia.org/wiki/Wildcard_DNS_record

    A wildcard DNS record is a record in a DNS zone that will match requests for non-existent domain names. A wildcard DNS record is specified by using a * as the leftmost label (part) of a domain name, e.g. *.example.com. The exact rules for when a wildcard will match are specified in RFC 1034, but the rules are neither intuitive nor clearly ...

  7. Reverse DNS lookup - Wikipedia

    en.wikipedia.org/wiki/Reverse_DNS_lookup

    For example, to do a reverse lookup of the IP address 8.8.4.4 the PTR record for the domain name 4.4.8.8.in-addr.arpa would be looked up, and found to point to dns.google. If the A record for dns.google in turn pointed back to 8.8.4.4 then it would be said to be forward-confirmed.

  8. TSIG - Wikipedia

    en.wikipedia.org/wiki/TSIG

    An update, as specified in RFC 2136, is a set of instructions to a DNS server. These include a header, the zone to be updated, the prerequisites that must be satisfied, and the record(s) to be updated. TSIG adds a final record, which includes a timestamp and the hash of the request.

  9. DNS zone transfer - Wikipedia

    en.wikipedia.org/wiki/DNS_zone_transfer

    RFC 1912 (section 2.2 SOA records) recommends using the value YYYYMMDDnn as the number (YYYY=year, MM=month, DD=day, nn=revision number). This won't overflow until the year 4294. Some DNS server packages have overcome this problem by automatically constructing the serial number from the last modification timestamp of the database file on disk.
