DNS zone transfer, also sometimes known by the inducing DNS query type AXFR, is a type of DNS transaction. It is one of the many mechanisms available for administrators to replicate DNS databases across a set of DNS servers .
The serial number is the time of last modification to the zone's data file expressed as the number of seconds since the UNIX epoch. This method is used by default in the djbdns suite. [ 7 ] Although it uses a 32-bit counter, it is not susceptible to the year 2038 problem due to the effect of serial number arithmetic .
The format of a zone file is defined in RFC 1035 (section 5) and RFC 1034 (section 3.6.1). This format was originally used by the Berkeley Internet Name Domain (BIND) software package, but has been widely adopted by other DNS server software – though some of them (e.g. NSD, PowerDNS) are using the zone files only as a starting point to compile them into database format, see also Microsoft ...
A graphical overview of all active DNS record types. This list of DNS record types is an overview of resource records (RRs) permissible in zone files of the Domain Name System (DNS). It also contains pseudo-RRs.
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 ...
dig is a network administration command-line tool for querying the Domain Name System (DNS). dig is useful for network troubleshooting and for educational purposes. [2] It can operate based on command line option and flag arguments, or in batch mode by reading requests from an operating system file.
Joe Rogan says he’s ‘genuinely concerned’ about drone sightings after new theory emerges
RPZ allows a DNS recursive resolver to choose specific actions to be performed for a number of collections of domain name data (zones). For each zone, the DNS service may choose to perform full resolution (normal behaviour), or other actions, including declaring that the requested domain does not exist (technically, NXDOMAIN), or that the user should visit a different domain (technically ...
