dig is a network administration command-line tool for querying the Domain Name System (DNS).. dig is useful for network troubleshooting and for educational purposes. [2] It can operate based on command line option and flag arguments, or in batch mode by reading requests from an operating system file.
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 ...
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.
ISATAP typically builds its Potential Router List (PRL) by consulting the DNS; hence, in the OSI model it is a lower-layer protocol that relies on a higher layer. A circularity is avoided by relying on an IPv4 DNS server, which does not rely on IPv6 routing being established; however, some network specialists claim that these violations lead to insufficient protocol robustness.
The server cannot handle the request (because it is overloaded or down for maintenance). Generally, this is a temporary state. [26] 504 Gateway Timeout The server was acting as a gateway or proxy and did not receive a timely response from the upstream server. 505 HTTP Version Not Supported The server does not support the HTTP version used in ...
dnsmasq caches DNS records, reducing the load on upstream nameservers and improving performance, and can be configured to automatically pick up the addresses of its upstream servers. dnsmasq accepts DNS queries and either answers them from a small, local cache or forwards them to a real, recursive DNS server.
As of 2004, it was the fourth most popular DNS server (counting BIND version 9 separately from versions 8 and 4) for the publication of DNS data. [2] Like various other DNS servers, Microsoft's DNS server supports different database back ends. Microsoft's DNS server supports two such back ends.
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.
