  2. Blackhole server - Wikipedia

    en.wikipedia.org/wiki/Blackhole_server

    The IANA-run servers were under increasing load from improperly-configured NAT networks, leaking out reverse DNS queries, also causing unnecessary load on the root servers. The decision was made by a small subset of root server operators to run the reverse delegations; each announcing the network using the autonomous system number of 112. [ 9 ]

  3. DNS over HTTPS - Wikipedia

    en.wikipedia.org/wiki/DNS_over_HTTPS

    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. [2]

  4. DNSCrypt - Wikipedia

    en.wikipedia.org/wiki/DNSCrypt

    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.

  5. Public recursive name server - Wikipedia

    en.wikipedia.org/wiki/Public_recursive_name_server

    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.

  6. DNS sinkhole - Wikipedia

    en.wikipedia.org/wiki/DNS_sinkhole

    A DNS sinkhole, also known as a sinkhole server, Internet sinkhole, or Blackhole DNS [1] is a Domain Name System (DNS) server that has been configured to hand out non-routable addresses for a certain set of domain names. Computers that use the sinkhole fail to access the real site. [2]

  7. Domain Name System - Wikipedia

    en.wikipedia.org/wiki/Domain_Name_System

    A DNS name server is a server that stores the DNS records for a domain; a DNS name server responds with answers to queries against its database. The most common types of records stored in the DNS database are for start of authority ( SOA ), IP addresses ( A and AAAA ), SMTP mail exchangers (MX), name servers (NS), pointers for reverse DNS ...

  8. Server Name Indication - Wikipedia

    en.wikipedia.org/wiki/Server_Name_Indication

    When a client uses domain fronting, it replaces the server domain in SNI (unencrypted), but leaves it in the HTTP host header (which is encrypted by TLS) so that server can serve the right content. Domain fronting violates the standard defining SNI itself, so its compatibility is limited (many services check that SNI host matches the HTTP ...

  9. DNS over TLS - Wikipedia

    en.wikipedia.org/wiki/DNS_over_TLS

    Android clients running Android Pie or newer support DNS over TLS and will use it by default if the network infrastructure, for example the ISP, supports it. [13] [14]In April 2018, Google announced that Android Pie will include support for DNS over TLS, [15] allowing users to set a DNS server phone-wide on both Wi-Fi and mobile connections, an option that was historically only possible on ...
