Requirements for DNS server

[LindyTaylor]

Hi

Let me know the minimum hardware requirement for DNS server? I know that depends on how many data stored, however, I would like to know proportional requirements for it. One more thing, what are the most important components?

To be very honest you don't need a fully formed dedicated server for only DNS. Personally, On our DNS server we are using powerdns that boud with cPanel and we run around 30 MB RAM for PDNS plus extra 30 MB for MySQL. That's it. Nowadays, most of the people have a few VPS's.

Hi

The actual requirements for DNS servers are very small unless you are not hosting e amount of domains on the same dedicated servers. In addition, there are few name servers that use MySQL, as a back end. In this kind of situation, you need to assign more RAM to your database server to cache queries and tables. Hence, that will reduce the loads even more.

I think, resource requirements will be very low, because a decent processor and 1 GB RAM is more than sufficient to run DNS servers. Although having a responsive DNS server will improve the experience of users when they visit your website, as a quick DNS look up. Overall, it means faster page load time.

In my opinion you really don't need a big dedicated server for a DNS server. I believe, VPS or classic dedicated server will do the job more adequately. I am using powerdns on a single core processor dedicated server with 2 GB RAM and honestly system load with a lot of DNS request is almost none.
