In Windows Server 2012, the Windows DNS added support for DNSSEC, [15] with full-fledged online signing, with Dynamic DNS and NSEC3 support, along with RSASHA and ECDSA signing algorithms. It provides an inbuilt key storage provider and support for any third party CNG compliant key storage provider.
The 160-bit and 256-bit digests generated by SHA1 and SHA-2 are more secure than the 128-bit digest generated by MD5. RFC 2930 defines TKEY, a DNS record used to distribute keys automatically from a DNS server to DNS clients. RFC 3645 defines GSS-TSIG, which uses gss-api and TKEY to distribute keys automatically in gss-api mode.
In computer networks, a reverse DNS lookup or reverse DNS resolution (rDNS) is the querying technique of the Domain Name System (DNS) to determine the domain name associated with an IP address – the reverse of the usual "forward" DNS lookup of an IP address from a domain name. [1]
Dynamic DNS is an expected feature or even requirement for IP-based security appliances like DVRs and IP cameras. [citation needed] Many options are available for today's manufacturer, and these include the use of existing DDNS services or the use of custom services hosted by the manufacturers themselves.
A validating stub resolver uses the CD bit to perform its own recursive authentication. Using such a validating stub resolver gives the client end-to-end DNS security for domains implementing DNSSEC, even if the Internet service provider or the connection to them is not trusted.
In Windows Vista (and Windows Server 2008) Microsoft moved the registration functionality from the DHCP Client service to the DNS Client service. Servers running Microsoft Windows also attempt to register other information, in addition to their names and IP addresses, such as the locations of the LDAP and Kerberos services that they provide.
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.
This is a list of notable managed DNS providers in a comparison table. A managed DNS provider offers either a web-based control panel or downloadable software that allows users to manage their DNS traffic via specified protocols such as: DNS failover, dynamic IP addresses, SMTP authentication, and GeoDNS.
