Connect Domain Name to VPS – no nameservers

This may not be the right place, so I’m willing to move the question.

I have a VPS from Virpus running Ubuntu 18.04 that I want to use to host a website. I have the Apache server already set up. I purchased a domain name from Namecheap. Now I need to set it up so that the domain name points to my server.

I thought it would be a simple task of adding the nameservers to my dashboard on Namecheap, so I went to my Virpus dashboard to locate the nameserver addresses. I wasn’t able to find them, however, so I contacted Virpus support. They told me they don’t offer a DNS service so I’d have to set this up with my domain registrar.

So now I’m not sure what to do. I know it must be possible but I’m really new to this kind of stuff. What’s the next step?

CNAME how-to?


I have a question about creating or setting up a CNAME record. Currently on my home router (that I own and manage), I am using one of the free DDNS services so that I can remotely connect back to my home router (running a VPN server) using a DNS name instead of my IP address. The service has been working great and there are no issues.

Here is what I’m trying to do now – at another location, I have cable modem service from my ISP and they own the cable modem with built in wireless gateway. Unfortunately they have disabled the DDNS section in the web GUI. I have read there is a work-around to this problem for my particular ISP. Apparently if you go to IPchicken.com, it returns a ‘Name Address’ that essentially points to my specific device and I can create something called a CNAME record for this.

I have no clue where to begin, or how to do that. I see that on the home page for the free DDNS service that I am currently using, there is support for A, AAAA, MX, NS, TXT, LOC, RP, HINFO, SRV, CAA as well as CNAME records. I don’t know if that means I can set this up there as well.

Thanks in advance!

DNS isnt getting changed even when chaging it in the network settings.

So my colege network (uses proxy) block various websites like porn, torrents etc, so to work around this i thought of changing the dns server in my laptop to in the network setting, but even after changing it when i go online to check my dns it shows the same as my college one’s. Is there any workaround for this? Why isnt my dns changing?

Single MySQL backend, multiple PowerDNS frontends

Hi Everyone,

What are the drawbacks to using a single MySQL database for two or more PowerDNS servers?

Currently I have 3 nameservers, all with a local MySQL database, in three different AWS regions. I am in the process of migrating to the Google Cloud and noticed that Google has a global private network, so an GCE instance in London can communicate with a GCE in Sydney using their addresses.

Other than latency, what are the downsides of having a single MySQL server, say in London, and having PowerDNS servers across the globe all accessing that single server?
