DNSrekordok

DNSrekordok is a term used in computing to refer to DNS records. DNS stands for Domain Name System, which is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network. It translates human-readable domain names, like www.example.com, into machine-readable IP addresses, such as 192.0.2.1. DNS records are individual entries within a DNS zone file that provide specific information about a domain name.

There are several types of DNS records, each serving a distinct purpose. The most common is the A record, which maps a hostname to an IPv4 address. The AAAA record serves a similar function but maps a hostname to an IPv6 address. The CNAME record, or Canonical Name record, creates an alias for another domain name. This means that multiple hostnames can point to the same IP address without needing to create separate A records for each.

Other important record types include MX records (Mail Exchanger), which specify the mail servers responsible for receiving email messages on behalf of a domain, and TXT records (Text), which allow administrators to store arbitrary text in DNS. TXT records are often used for verification purposes, such as proving ownership of a domain for services like Google Workspace, or for implementing security policies like SPF (Sender Policy Framework). NS records (Name Server) indicate the authoritative name servers for a domain. Understanding DNSrekordok is crucial for network administration, website management, and troubleshooting connectivity issues.
