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.
nslookup operates in interactive or non-interactive mode. When used interactively by invoking it without arguments or when the first argument is - (minus sign) and the second argument is a hostname or Internet address of a name server, the user issues parameter configurations or requests when presented with the nslookup prompt (>).
For example, to do a reverse lookup of the IP address 8.8.4.4 the PTR record for the domain name 4.4.8.8.in-addr.arpa would be looked up, and found to point to dns.google. If the A record for dns.google in turn pointed back to 8.8.4.4 then it would be said to be forward-confirmed.
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 ...
ipconfig (standing for "Internet Protocol configuration") is a console application program of some computer operating systems that displays all current TCP/IP network configuration values refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings. [1]
MaraDNS is a free software DNS server by Sam Trenholme that claims a good security history and ease of use. [9] [10] In order to change any DNS records, MaraDNS needs to be restarted. Like djbdns dnscache, the MaraDNS 2.0 stand-alone recursive resolver ("Deadwood") does not use threads.
Like the DNS, it is implemented in two parts, a server service (that manages the embedded Jet Database, server to server replication, service requests, and conflicts) and a TCP/IP client component which manages the client's registration and renewal of names, and takes care of queries. Basically, Windows Internet Name Service (WINS) is a legacy ...
Prior to Windows Vista (and Windows Server 2008), this registration is performed by the DHCP Client service. It is thus necessary to run the DHCP Client service on pre-Vista machines, even if DHCP isn't being used to configure the machine in order to dynamically register a machine's name and address for DNS lookup. The DHCP Client service ...
