Setting up DNSSEC on a Namecheap domain hosted on UpCloud using CloudFlare

July 15, 2018 by Simon

This is how I set up DNSSEC on a Namecheap domain hosted on UpCloud using CloudFlare to setup DNS security extensions

If you have not read my previous posts I have now moved my blog to the awesome UpCloud host (signup using this link to get $25 free UpCloud VM credit). I compared Digital Ocean, Vultr and UpCloud Disk IO here and UpCloud came out on top by a long way (read the blog post here). Here is my blog post on moving from Vultr to UpCloud.

About DNSSEC

Wikipedia has a great write-up on DNSSEC also read the ICANN page on DNSSEC.

Snip “DNSSEC is a set of extensions to DNS which provide to DNS clients (resolvers) origin authentication of DNS data, authenticated denial of existence, and data integrity, but not availability or confidentiality.”

https://daniellbenway.net has a great video explaining DNSSEC

  • Cloudflare – How does DNS Sec Work?

Let’s view my DNSSEC status now

Prerequisites

This guide assumes you have already purchased a domain and set it up with say UpCloud hosting (read my setup guide here).

Buy a domain name from Namecheap here.

Domain names for just 88 cents!

Read my old guide here that I created while setting up Cloudflare on the Vultr host to see how to setup Cloudflare.

Setting up DNSSEC

First I logged into My Namecheap account, selected my domain, selected Advanced DNS and enabled DNSSEC.

Screenshot of Namecheap Advanced DNS page

I can see a number of values for DNSSEC KeyType/Algorithm/Digest Type and Digest. Below are the options in the dropdowns for Algorithm and Digest Type.

DNSSEC Algorithms

DNSSEC Algorithms (RSA, MD5 etc)

DNSSEC Digest Types

DNSSEC Digest Types (SHA etc)

I contacted NameCheap support and they said I needed to contact my UpCloud hosts to get relevant DNSSEC values.

My domain was purchased at NameCheap but by domain routers by Cloudflare DNS.

Namecheap DNS Nameservers pointing to cloudflare

By chance, I logged into my Cloudflare account and noticed they have a DNSSEC section under DNS. Nice.

Screenshot of Cloudflare menu, DNS highlighted.

I enabled DNSSEC

Enable Cloudflare DNSSEC records

Cloudflare offers all the relevant DNSSEC values.

Screenshot of Cloudflare DNSSEC generated Values

I entered these values into Namecheap under Advanced DNS on my domain.

After 5 mins re-ran the DNSSEC Analyzr tool.

Screenshot of http://dnssec-debugger.verisignlabs.com/ Results

Hmmm, Cloudflare seems to think something is wrong 🙁

Screenshot of Cloudflare saying DNSSEC is not configured

I ran a DNS DS Lookup on my site. Everything appears ok.

Screenshot of https://mxtoolbox.com/SuperTool.aspx?action=mx

I re-added the record in Namecheap and waited for 15 mins and this time Cloudflare was happy. Maybe I just needed to wait for DNS replication a little longer?

Screenshot of cloudflare showing DNSSEC is all ok.

I tested my DNS serves with DNS Root Canary

DNS test with https://rootcanary.org/

I tested my site’s DNSSEC with https://zonemaster.iis.se/

Screenshot of https://zonemaster.iis.se/

Done

Skipping Cloudflare

I found that I can simply skip Cloudflare by enabling Premium DNS at Namecheap

Then enabling DNSSEC

Easy (totally independent of Cloudflare)
