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.
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 ...
DNS over HTTPS (DoH) is a protocol for performing remote Domain Name System (DNS) resolution via the HTTPS protocol. A goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks [1] by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver.

In 32- and 64-bit releases of Windows 7, some older but still available versions of Bonjour services can disable all network connectivity by adding an entry of 0.0.0.0 as the default gateway. This was a bug reported in 2013. [13] The open-source IM clients Pidgin, Kopete and Adium support the Bonjour IM protocol, as does the closed-source ...
Mozilla will bring its new DNS-over-HTTPS security feature to all Firefox users in the U.S. by default in the coming weeks, the browser maker has confirmed. It follows a year-long effort to test ...
MaraDNS is a free software DNS server by Sam Trenholme that claims a good security history and ease of use. [9] [10] In order to change any DNS records, MaraDNS needs to be restarted. Like djbdns dnscache, the MaraDNS 2.0 stand-alone recursive resolver ("Deadwood") does not use threads. [11]
Dynamic DNS updates use the UPDATE DNS opcode to add or remove resource records dynamically from a zone database maintained on an authoritative DNS server. [40] This facility is useful to register network clients into the DNS when they boot or become otherwise available on the network.
Both IPv4 and IPv6 hosts may randomly generate the host-specific part of an autoconfigured address. IPv6 hosts generally combine a prefix of up to 64 bits with a 64-bit EUI-64 derived from the factory-assigned 48-bit IEEE MAC address. The MAC address has the advantage of being globally unique, a basic property of the EUI-64.
