Nameserver converts domain names (www.example.com) into IP addresses (192.168.1.1). This process is essential for computers to communicate on the internet, as devices identify each other using IP addresses.
Nameservers often cache previously resolved domain-to-IP mappings to improve efficiency and reduce the response time for repeated queries.
Nameservers store information about domains in zone files. These files contain records such as A (address) records, which map domain names to IP addresses, and other DNS record types.
Some advanced nameservers support load balancing by distributing incoming DNS queries among multiple servers. This helps distribute the workload.
Nameservers are essential for DNS security. Various mechanisms, such as DNS Security Extensions, are implemented to ensure the integrity and authenticity of DNS data.
