In this article from the TripleZero iT Hosting knowledge base we explain: What is DNSSEC and how do I add it to my domain?. We describe the purpose, the preparation and a clear method that you can follow step by step.
This manual is written for customers of TripleZero iT Hosting and assumes common configurations on shared hosting, reseller environments and control panels such as DirectAdmin, CyberPanel and Plesk.
What you need
- Access to the customer panel or the TripleZero iT Hosting customer panel.
- Your domain name and any login/mailbox details.
- A current browser and, where applicable, FTP/SSH access.
- Preferably a recent backup before making structural changes.
Step-by-step approach
- Log in to the appropriate panel at TripleZero iT Hosting and select the domain or account affected by the change.
- Check that you have the correct environment (production vs. test) and note the current settings.
- Perform the action that corresponds to “What is DNSSEC and how do I add it to my domain?”. Work calmly and do not change multiple critical options at the same time.
- Save changes and test the result: website, email or DNS — depending on the subject.
- Document what you changed so you can roll back later or help support more quickly.
Deeper explanation
The topic “What is DNSSEC and how do I add it to my domain?” often affects multiple layers: DNS, web server, mail server, application (e.g. WordPress) and account limits. Problems usually arise when one layer is changed without checking the others.
For TripleZero iT Hosting, we recommend first verifying that DNS points to the correct name servers, then checking control panel settings, and only then changing application settings (plugins, themes, .htaccess).
DNS and registration aspects
In this topic, DNS or domain registration plays a central role. Check name servers, TTL and whether changes are already visible worldwide before concluding that something “doesn't work”.
Preferably work with a single source of truth for DNS: either TripleZero iT Hosting name servers, or an external DNS provider — not both half-configured.
DNS records in practice
Open DNS management in the customer panel or DirectAdmin/CyberPanel/Plesk. Change one record at a time, write down the old value, and wait for propagation before concluding that something failed.
For CNAME: do not use CNAME on the apex (@) unless your provider supports ALIAS/ANAME. A records point to an IPv4 address; AAAA to IPv6.
Post-completion checklist
- Does the website work over HTTP and HTTPS without certificate errors?
- Are test emails delivered and not marked as spam?
- Are limits (disk, inodes, bandwidth) still within the package limits?
- Are there no unintentional redirects, firewall blocks or PHP errors in the logs?
Common bottlenecks
- DNS propagation: changes are not immediately visible everywhere.
- Wrongly selected domain or user in a reseller environment.
- Cache (browser, CDN, LiteSpeed/OpenLiteSpeed, WordPress plugins) showing old content.
- Missing permissions on directories or wrong document root.
