DNSSEC also provides a level of additional security so the web browser can check to make sure the DNS information is correct and not corrupted. Similar to the digital signature at the bottom of an e-mail, DNSSEC use key cryptography to authenticate DNS response data and ensure it came from the correct sender (DNS server). Your computer takes the text-based name and uses internet DNS servers to perform the translation to the IP of your website.ĭNSSEC – DNS Security Extensions (DNSSEC) were created by the domain industry to add more security measures to DNS to help verify and authenticate data. Instead of memorizing each phone number, all you have to do is type the name that corresponds to the phone number to send a text, or in this case access a website. Think of DNS as a cell phone that holds contact information. DNS matches the name of a website (text-based names) to the corresponding address for the website (numeric Internet location also known as an IP address) in order to help make the internet more user friendly. Now that we’ve covered the fundamental elements of the domain industry, let’s tackle some of the more technical and complex terms, in particular as it relates to domain security online which is a top priority within the domain and internet communities.ĭNS – We briefly mentioned DNS in the second post of this series, but for more background, the domain name system (DNS) is a naming system that provides the framework for internet browsing. The second post in the series, Domain Lingo 101: Who’s Who in the Industry, highlighted the key players in the domain industry and the roles they play in the overall management of the internet. In Domain Lingo 101: Let’s Start With The Basics, we learned what a domain name is and a few of the most popular types of domains. Hopefully you’ve built up a foundational understanding of the domain industry through the first two posts of this series. When it comes to the ins and outs of the internet, things can get technical quickly. By Tony Connor, Director of Product Marketing, Public Interest Registry
