An example of an IP addresses in the reverse DNS zone is 166.188.77.208.in-addr.arpa, which represents the address 208.77.188.166 and resolves to the domain name www.example.com. In the case of IP addresses, the reverse zones are delegated to the Internet service provider (ISP) to which the IP address block is assigned.
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 ...
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. It also contains pseudo-RRs. Resource records

For example, the A record is used to translate from a domain name to an IPv4 address, the NS record lists which name servers can answer lookups on a DNS zone, and the MX record specifies the mail server used to handle mail for a domain specified in an e-mail address.
No wildcard will match because subdel.example. exists and is a zone cut, putting host.subdel.example. into a different DNS zone. Even if host.subdel.example. does not exist in the other zone, a wildcard will not be used from the parent zone. ghost.*.example. MX No wildcard will match because *.example. exists, it is a wildcard domain, but it ...
For instance, in the FQDN somehost.example.com, com is a label directly under the root zone, example is nested under com, and finally somehost is nested under example.com. [ 3 ] The topmost layer of every domain name is the DNS root zone , which is expressed as an empty label and can be represented in an FQDN with a trailing dot, such as ...
Like the CNAME record, the DNS lookup will continue by retrying the lookup with the new name. The name server synthesizes a CNAME record to actually apply the DNAME record to the requested name—CNAMEs for every node on a subtree have the same effect as a DNAME for the entire subtree. For example, if there is a DNS zone as follows:
