A domain name system (DNS) is a set of records that maps human-readable <\/span>domain names<\/span><\/a> to IP addresses. For example, if you want to know the IP address for your domain name www.example.com, the DNS records will show you.<\/span><\/p>\n

It\u2019s important for businesses to monitor their DNS because it can indicate a problem, such as a Distributed Denial-of-Service (DDOS) attack.<\/span><\/p>\n

If a DNS attack is in progress, it can cause your site to go down or even block access entirely. The good news is <\/span>DNS checks<\/span> can prevent such mishaps from happening.<\/span><\/p>\n

A Little Look Back About DNS<\/span><\/b><\/h2>\n

When the internet was still in its infancy, people had to enter the IP addresses of websites they were trying to search in the browser. As more and more websites launched online, it became impossible to remember their IP addresses.<\/span><\/p>\n

Even if one could remember the IP addresses of their most frequented sites, they could receive an error if the IP address of that website changed. There was a desperate need for a solution, and then came the DNS.<\/span><\/p>\n

You see, humans are good at remembering names, and machines operate on numbers. DNS translates human-readable website names into IP addresses. Computers use them to communicate with one another.<\/span><\/p>\n

Furthermore, companies can now easily update their DNS records.\u202f<\/span><\/p>\n

Simple enough. So, what’s the problem?<\/span><\/p>\n

Despite the numerous benefits of the internet, it\u2019s also a playfield for hackers. DNS is a critical piece of infrastructure on the internet but is not impervious to security threats.<\/span><\/p>\n

Hackers and malware creators have found ways to exploit flaws in DNS to steal your personal information and interrupt internet service.<\/span><\/p>\n
