DNSCurve is a proposed secure protocol for the Domain Name System (DNS), designed by Daniel J. Bernstein. It encrypts and authenticates DNS packets between resolvers and authoritative servers. DNSCurve claims advantages over previous DNS services of: [1] Confidentiality—usual DNS requests and responses are not encrypted, and broadcast to any ...
A public recursive name server (also called public DNS resolver) is a name server service that networked computers may use to query the Domain Name System (DNS), the decentralized Internet naming system, in place of (or in addition to) name servers operated by the local Internet service provider (ISP) to which the devices are connected.
The Link-Local Multicast Name Resolution (LLMNR) is a protocol based on the Domain Name System (DNS) packet format that allows both IPv4 and IPv6 hosts to perform name resolution for hosts on the same local link.
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 ...
DNSCrypt is a network protocol that authenticates and encrypts Domain Name System (DNS) traffic between the user's computer and recursive name servers.DNSCrypt wraps unmodified DNS traffic between a client and a DNS resolver in a cryptographic construction, preventing eavesdropping and forgery by a man-in-the-middle.
Unbound is designed as a set of modular components that incorporate modern features, such as enhanced security validation, Internet Protocol Version 6 (IPv6), and a client resolver application programming interface library as an integral part of the architecture.
EDNS Client Subnet (ECS) is an option in the Extension Mechanisms for DNS that allows a recursive DNS resolver to specify the subnetwork for the host or client on whose behalf it is making a DNS query.
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 ...
