Signature record used in SIG(0) (RFC 2931) and TKEY (RFC 2930). [7] RFC 3755 designated RRSIG as the replacement for SIG for use within DNSSEC. [7] SMIMEA 53 RFC 8162 [9] S/MIME cert association [10] Associates an S/MIME certificate with a domain name for sender authentication. SOA: 6 RFC 1035 [1] and RFC 2308 [11] Start of [a zone of ...
While protecting IP addresses is the immediate concern for many users, DNSSEC can protect any data published in the DNS, including text records (TXT) and mail exchange records (MX), and can be used to bootstrap other security systems that publish references to cryptographic certificates stored in the DNS such as Certificate Records (CERT ...
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.
This is a partial list of RFCs (request for comments memoranda). A Request for Comments (RFC) is a publication in a series from the principal technical development and standards-setting bodies for the Internet, most prominently the Internet Engineering Task Force (IETF).
Extension Mechanisms for DNS (EDNS) is a specification for expanding the size of several parameters of the Domain Name System (DNS) protocol which had size restrictions that the Internet engineering community deemed too limited for increasing functionality of the protocol.
A zone transfer uses the Transmission Control Protocol (TCP) for transport, [1] [2] and takes the form of a client–server transaction. The client requesting a zone transfer may be a secondary server requesting data from a primary server. [3] The portion of the database that is replicated is a zone.
When an authoritative name server receives a DNS query, it takes advantage of ECS DNS extension to resolve the hostname to a CDN which is geolocationally near to the client IP's subnet, hence the client makes further requests to a nearby CDN, thereby reducing latency. The EDNS client subnet mechanism is specified in RFC 7871.
A Name Authority Pointer (NAPTR) is a type of resource record in the Domain Name System of the Internet. [1] [2]NAPTR records are most commonly used for applications in Internet telephony, for example, in the mapping of servers and user addresses in the Session Initiation Protocol (SIP).
