What is DNS and Why is it Important?
Simply put, DNS (the Domain Name System) converts text-based, human-readable domain names like www.liquidweb.com into an IP (Internet Protocol) address like 184.108.40.206. This system also works in an inverse manner and converts IP addresses into domain names. When internet-connected devices communicate, IPs are utilized to find and connect to a specified destination. This simply means that the DNS protocol acts as an “internet phone book” of sorts that translates the text-based domain name you enter in your favorite browser into that device ready IP. Because of the limited availability of IPv4 IP addresses, keeping all the internet-ready devices connected becomes even more challenging. This has caused the rise and proliferation of IPv6 addresses. These IP addresses, which look like “2a03:2880:f127:283:face:b00c:0:25de” are continuing to be more widely used.
