DNS management
Change only the records supplied by the service you are connecting
DNS controls where your website and email are delivered. Record the existing values first and avoid replacing nameservers when a small record change is all that is required.
Choose the correct DNS manager
UKC parked domain
Open My Domains, choose the domain and use DNS Manager in the domain control centre.
Shared hosting domain
Open Plesk, select Websites and Domains, then DNS Settings for the domain.
Common record types
| Type | Purpose | Typical value |
|---|---|---|
| A | Website or service IPv4 address | An address such as 192.0.2.10 |
| AAAA | IPv6 address | An IPv6 address |
| CNAME | Alias for a hostname | A destination hostname, not a URL |
| MX | Incoming email server | Priority plus a mail hostname |
| TXT | Verification and email policy | SPF, DKIM, DMARC or service text |
Safe change process
Copy current records
Take a screenshot or export before editing.
Change the smallest scope
Add or edit only the exact host and type supplied.
Allow propagation
Caches can retain the previous result until their TTL expires.
Microsoft 365 and Google Workspace
Use the current records shown in the provider admin centre. Do not copy values from an unrelated guide or another domain, because verification and DKIM values can be domain-specific.
Next step
Manage your domain connection settings
Open the correct DNS manager and keep a copy of the previous records.
