Answer: DNS is the acronym for the domain name server. A server is a dedicated computer system that translates name requests or queries to Internet Protocol (IP) addresses.

Q #2) What does a DNS server do?

Answer: The DNS server contains a list of public IP addresses associated with hostnames. It translates web addresses such as abc.com into IP addresses that are in a numerical format. In addition, DNS apps can also filter adult content, phishing sites, advertisements, and malware.

Q #3) What are the main types of DNS servers?

Answer: The main types of DNS servers include primary and secondary servers. The primary DNS server is the preferred server, while the secondary DNS server is the alternate server. The two servers provide an extra layer of redundancy and maximize uptime.
