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.
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

Let’s view my DNSSEC status now
https://dnssec-analyzer.verisignlabs.com/ can help you check your sites DNSSEC status.
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.
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.
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 Digest Types
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.
By chance, I logged into my Cloudflare account and noticed they have a DNSSEC section under DNS. Nice.
I enabled DNSSEC
Cloudflare offers all the relevant DNSSEC values.
I entered these values into Namecheap under Advanced DNS on my domain.
After 5 mins re-ran the DNSSEC Analyzr tool.
Hmmm, Cloudflare seems to think something is wrong 🙁
I ran a DNS DS Lookup on my site. Everything appears ok.
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?
I tested my DNS serves with DNS Root Canary
I tested my site’s DNSSEC with https://zonemaster.iis.se/
I found that I can simply skip Cloudflare by enabling Premium DNS at Namecheap
Then enabling DNSSEC
Easy (totally independent of Cloudflare)
