It's during this DNS address "look up" where you can experience problems in performance, accessibility and security - everything from your domain not being found to hackers redirecting your visitors to a fake website in order to steal their personal information.

Slow DNS response can cause "website not found" errors

Have you ever typed in a website address and it takes a long time to connect? Or maybe you get a "site not found" error? This can happen when the DNS server is slow in responding and can't determine what site content to give you. If it takes too long, it can just "time out" and give an error message.

Hackers can redirect your visitors to a fake site

An even scarier issue is when a hacker interferes in the look up process – a vulnerability that exists with all DNS systems worldwide. Hackers can actually give the browser a different IP address that redirects your visitors to a fake website that looks like yours. Once your visitors are there, the hacker will be able to access any information your customer provides, from usernames and passwords to credit card numbers.
