At Openprovider, DNS management is a service that is available free of charge to Openprovider customers. Use our geographically separated name servers for optimal security or use them as fallback for your own name servers.
With Openprovider's nameservers you are assured of a high-quality and stable solution. And you can decide for yourself to what extent you use our nameservers: you can use our master nameservers, use our servers as slave nameservers, or just use your own servers for everything.
Openprovider operates domain name servers from geographically separated locations (Ireland, United Kingdom and Germany), in separate subnets, using hardware of the highest quality. This allows the system to recover immediately if any failures occur, ensuring that your web sites and email continue operating. Our servers run the most up-to-date software, and our dedicated team of system engineers is always ready to respond to issues when they arise.
Service level agreement
The use of the free Openprovider nameservers comes without service level agreement (SLA). We do our best to keep the services up at any moment, but we can not guarantee a minimum uptime. History has learned that our nameservers are highly reliable, however there may be situations where you can experience degraded performance, for example in case of a DDoS attack.
Attacks on nameservers (DDoS)
A DDoS (distributed denial-of-service) happens when thousands of queries per second are done (usually from different IP-addresses) on 1 domain name. When the amount of queries are bigger than the capacity to process those queries and the requests keep coming, the availability of the nameservers may be affected.
Every system which will process queries could be affected by a DDoS attack. This can not be fully prevented by the administrator of the service. More information about DDoS attacks can be found here
Precautions to prevent those attacks.
Although we can not fully prevent DDoS attacks, we have taken several precautions to reduce the risks.
To prevent those attacks we have placed a fair limit on the number of queries per second per IP address. This limit will be reviewed on a regular basis.
If our monitoring detects more the the allowed limit of queries from 1 IP address on our nameservers, those queries will be banned in order to prevent possible problems.
