Can I set up DNS proxy on same droplet as my Wordpress site?

Posted September 15, 2014 2.8k views

We subscribe to Netflix, and we would like to be able to access the U.S. movie inventory when we are out of the country. I understand that I can do that by either setting up a VPN or a DNS proxy. The proxy seems preferable because only the authentication goes through the proxy, not the streaming of the movies themselves, as they would with a VPN. I found information online about how to set up a DNS proxy on a clean CentOS droplet, and the instructions seem pretty straightforward. I already have a droplet on a DigitalOcean server in New York, and I am running my low-volume WordPress website on it using Ubuntu 12.04 and nginx. Being able to do this is not worth the time and expense of setting up a new droplet. Can I safely add the DNS proxy to the same droplet that I am running my website on? Are there any considerations I should be aware of? Thank you for any insight you can share on this.

Even a small WordPress site can use up most of a servers resources, depending on the plugins installed.

With that said, DNS takes up almost no resources, but be aware: unless you lock it down to your subnet/IP at your house, others can use your DNS server, potentially for illegal activity/attacks, which could bring your server down, or cause DO to disable it.

I have a BIND server at my office for testing, and the OS and BIND combined only use 136MB of RAM, if that’s an indicator as to the resources required. With 10 servers hitting it, BIND uses ~8MB

Thank you for your response. Is it possible to lock the DNS down to a private subnet/IP while still allowing public access to my website?
