Use this when Help4 is managing DNS, CDN routing, virtual patching, WAF policy, and full-proxy coverage for the whole domain. The goal is simple: move the domain to Help4 nameservers without breaking email, SSL, or your origin site.
Replace the existing registrar nameservers with all six Help4 nameservers:
ns1.help4.net
ns2.help4.net
ns3.help4.net
ns4.help4.net
ns5.help4.net
ns6.help4.net
ns1.help4.net and ns2.help4.net, then open a Help4 ticket so we can verify redundancy and registrar limits.ns1.help4.net through ns6.help4.net.After saving the registrar change, check the authoritative nameservers:
dig +short NS example.com
You should eventually see only Help4 nameservers:
ns1.help4.net.
ns2.help4.net.
ns3.help4.net.
ns4.help4.net.
ns5.help4.net.
ns6.help4.net.
Load the home page, a product or landing page, a post, and a file from /wp-content/uploads/. Help4 should serve traffic while keeping the origin reachable as fallback.
Send and receive a test message. If mail stops, compare MX/TXT/SPF/DKIM/DMARC records against the pre-change screenshot or export.
These two issues cause many cutover problems and they are easy to miss.
If the old DNS provider had DNSSEC enabled, the registrar may still publish an old DS record. Remove the old DS record before switching, or ask Help4 to provide the correct DNSSEC values after the Help4 zone is signed.
If the domain shows clientHold, serverHold, or unpaid/suspended status at the registrar, nameserver changes may not take effect until the registrar clears the hold.
| Symptom | Likely cause | What to do |
|---|---|---|
| Registrar will not save all six nameservers. | Registrar has a two- or four-NS limit. | Enter the allowed Help4 nameservers, then ask Help4 to verify delegation health. |
| Site still resolves to the old provider. | Registry update or resolver cache has not settled. | Check dig +trace example.com NS and wait for recursive caches to refresh. |
| Website works, email breaks. | MX, SPF, DKIM, DMARC, or mail subdomain records were not copied. | Restore email records from the pre-change export in Help4 DNS. |
| Some users see DNSSEC validation failures. | Old DS record still points to the old DNS provider. | Remove the old DS record at the registrar or coordinate the Help4 DNSSEC values. |
| Nameserver change does not publish. | Domain has a registrar hold or billing/suspension status. | Clear the hold with the registrar, then save the nameserver change again. |
If you are not ready to move nameservers, install the Help4 CDN WordPress plugin first. Plugin-first mode can rewrite approved assets to Help4 CDN and sync cache refresh requests without delegating the whole DNS zone.
