TKEY (transaction key) is a record type of the Domain Name System (DNS). TKEY resource records (RRs) can be used in a number of different modes to establish shared keys between a DNS resolver and name server .
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 ...
A TXT record (short for text record) is a type of resource record in the Domain Name System (DNS) used to provide the ability to associate arbitrary text with a host or other name, such as human readable information about a server, network, data center, or other accounting information.
Returns all records of all types known to the name server. If the name server does not have any information on the name, the request will be forwarded on. The records returned may not be complete. For example, if there is both an A and an MX for a name, but the name server has only the A record cached, only the A record will be returned.
DNS-SD (DNS Service Discovery [16]) allows clients to discover a named list of service instances and to resolve those services to hostnames using standard DNS queries. The specification is compatible with existing unicast DNS server and client software, but works equally well with mDNS in a zero-configuration environment.
The use of a key shared by the client making the update and the DNS server helps to ensure the authenticity and integrity of the update request. A one-way hashing function serves to prevent malicious observers from modifying the update and forwarding on to the destination, thus ensuring integrity of the message from source to destination.
BIND, the most popular DNS name server (which includes dig), incorporates the newer DNSSEC-bis (DS records) protocol as well as support for NSEC3 records. Unbound is a DNS name server that was written from the ground up to be designed around DNSSEC concepts. mysqlBind, the GPL DNS management software for DNS ASPs, now supports DNSSEC.
Because the DHCP server provides the DHCP client with server IP addresses, such as the IP address of one or more DNS servers, [8]: sec. 7 an attacker can convince a DHCP client to do its DNS lookups through its own DNS server, and can therefore provide its own answers to DNS queries from the client.
