Each of these DNS servers is an independent implementation of the DNS protocols, capable of resolving DNS names for other computers, publishing the DNS names of computers, or both. Excluded from consideration are single-feature DNS tools (such as proxies, filters, and firewalls) and redistributions of servers listed here (many products ...
Unbound is a validating, recursive, and caching DNS resolver product from NLnet Labs. It is distributed free of charge in open-source form under the BSD license . Features
The owner of self-serve web archiving tool Archive.today has expressed concern over Cloudflare 1.1.1.1 not passing the contents of this field on to the authoritative DNS server for Archive.today, and has in response configured the site's authoritative DNS servers to consider Cloudflare DNS requests invalid—effectively blocking 1.1.1.1 from resolving the website DNS records.
Wildcards in the DNS are much more limited than other wildcard characters used in other computer systems. Wildcard DNS records have a single * (asterisk) as the leftmost DNS label, such as *.example.com. Asterisks at other places in the domain will not work as a wildcard, so neither *abc.example.com nor abc.*.example.com work as wildcard DNS ...
Multicast DNS (mDNS) is a computer networking protocol that resolves hostnames to IP addresses within small networks that do not include a local name server.It is a zero-configuration service, using essentially the same programming interfaces, packet formats and operating semantics as unicast Domain Name System (DNS).
Your domain is not activated in the DNS. If you provided delegation information (name servers), this status may indicate an issue with your domain that needs resolution. If so, you should contact your registrar to request more information. Suppose your domain has no issues, but you need it to resolve in the DNS.
The modern "reverse DNS lookup" should not be confused with the now-obsolete "inverse query" (IQUERY) mechanism specified in RFC 1035: Inverse queries take the form of a single resource record (RR) in the answer section of the message, with an empty question section. The owner name of the query RR and its time to live (TTL
DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. [1] This can be achieved by malware that overrides a computer's TCP/IP configuration to point at a rogue DNS server under the control of an attacker, or through modifying the behaviour of a trusted DNS server so that it does not comply with internet standards.
