What’s the DNS and Why’s It Got a Flag Day?
Think of the DNS (Domain Name System)
Now, imagine that not only have lots more users been added to this digital phonebook but also extra information as well, such as addresses, zip codes etc. But some parts were not updated. So now the phonebook has to be compatible with both new and old info. Now, also imagine that there are restrictions on what the phonebook can hold, such as limits to username fields and column numbers. Having to check multiple versions would slow everything down and prevent better features from being added.
And that’s what’s happened. The DNS needs a clear-out.
That’s what DNS Flag Day basically is: a global DNS clear out—scheduled to happen on 1 February 2019. The workarounds and extra checks that once helped websites running non-compliant software will no longer work—they were slowing everything down and endangering the system from a security standpoint. But if your DNS provider is already 100% compliant with the industry requirements (like Namecheap!), you can relax.
Why the Updates Now?
The DNS system was created back in the 1980s. Since then, it’s grown, but the rate of growth was quite slow until fairly recently. With the Internet now powering change and digital innovation across just about every industry, growth has hit the fast lane. More users. More domains. More IP addresses. More features. This means legacy systems are really starting to weigh progress down.
Older systems are also a security risk, potentially exposing important customer data—a major concern for organizations worldwide.
Let’s Get Techie… What Exactly Will Happen?
After Flag Day, DNS Servers must comply with EDNS (Extension mechanisms for DNS). They will no longer respond to legacy DNS requests. If you don’t have compliant servers or software, your online presence will slowly degrade, and the website will stop working once the DNS system update is made.
EDNS is being supported by all the major DNS players, including Google and Cisco. So, there’s no escaping DNS Flag Day if your website or business is not compliant.
