DNS servers translate the website domain names users search in web browsers into corresponding numerical IP addresses. This process is known as DNS resolution.
This is the final stop for the DNS query. This nameserver receives the DNS resolver’s query and pulls up the DNS A Record to retrieve Google’s numerical address. However, if a domain or a subdomain has an alias — like Google.com — the DNS resolver will receive that information first...
The software for setting up a DNS server isfreely available, allowing anyone with the technical knowledge to create one for themselves. By default, however, your devices will send DNS queries to DNS servers run by your internet provider (ISP). IPv4 and IPv6 IP addresses come in two versions...
A DNS monitor can also check and verify other records contained in your DNS, such as MX and NS records. Monitor both IPv4 and IPv6 Just because both protocols route to the same server doesn’t mean that both protocols work. Explicitly monitoring IPv6 and IPv4 is possible with uptime ...
One reason IPv6 is replacing IPv4 is that it provides a larger number of IP addresses than IPv4. When multiple devices on the same network are connected to the internet, it's important that there's a unique address available for each device. ...
The biggest drawback is that both protocols cannot communicate with each other. So, an IPv4-only device cannot connect directly to an IPv6-only device. However, individual devices can currently support both IPv4 and IPv6. Dual-stack IP, for instance, allows a single router, server, or switc...
DNS recursor - The recursor can be thought of as a librarian who is asked to go find a particular book somewhere in a library. The DNS recursor is a server designed to receive queries from client machines through applications such as web browsers. Typically the recursor is then responsible fo...
It is by a domain’s IP address that devices can connect with one another. What is a DNS Server? Of course, DNS isn’t just manifested out of thin air. It does have a physical location. The domain name system operates via DNS nameservers that are strategically positioned across the ...
DNS Server A DNS server maps a domain name to an IP address. The DNS server stores a table of domain names and correspondingIPaddresses to resolve the domain names of messages. Because the Internet is a collection of globally connected resources, and a single DNS server cannot support all ad...
A domain name system (DNS) is a system that stores domain information in adistributed database. The main function of a DNS is to translatedomainnames intoIP addressesand vice versa. DNS enables using easy-to-remember domain names instead of IP addresses for each website or server. ...
