What is the DNS Flag Day?
The Domain Name System (DNS) was born in the 1980s and the first DNS Extension Protocol Specification (EDNS) was developed in 1990. Although the specifications were formulated nearly 30 years ago, some hosts still do not support the EDNS protocol, which has caused other hosts to make additional countermeasures for this, slowing down the DNS speed and limiting the new features of the DNS. For this reason, DNS vendors and large public DNS service providers will delete these old processes on the “DNS Flag Day” day.
When is the DNS Flag Day?
The update will be implemented on February 1, 2019.
How should I do?
If you are a regular user, don’t worry, it will have no direct impact on your browsing of the website.
If you have a domain name, you have to pay attention. You must confirm that the DNS server you are currently using is compliant with the EDNS protocol. Otherwise the primary DNS provider will stop supporting your domain name and your customers will not be able to connect to your website.
How to check whether the server supports EDNS?
You can test your server for compliance by entering the domain name in the DNS Flag Day tool (https://dnsflagday.net).
You can also contact the Kitcle Professional Team for assistance directly.
If you are currently a Kitcle client, please don’t worry about DNS Flag Day, because we have set up a server for each site. That’s it!
