DNS-update incoming: is your domain ready?

by | 11-01-2019 | News

Let’s talk DNS. In the very essence, the Domain Name System is a global, decentralised system that links a domain name (such as www.cybersprint.com) to an IP-address. Just like everything else IT, it is best when updated regularly. To make the current DNS ready for extension mechanisms (EDNS), certain workarounds are going to be deleted starting 1 February 2019.

Will this effect your domain? Test it here.

The main change is that DNS software from certain vendors interpret timeouts as sign of a network or server problem. Starting February 1st, 2019 there will be no attempt to disable EDNS as reaction to a DNS query timeout.

This effectivelly means that all DNS servers which do not respond at all to EDNS queries are going to be treated as dead.

The site dnsflagday.net offers a free check for your domains. Next to the one-click check, the site lists more ways to check your compatibility. The update only affects sites running on software that doesn’t follow the published standards. Still, better safe than sorry.
