An A record should only be updated when you know which record needs changing and have been given the correct destination value. Provider dashboards differ, but the general process is similar.
Before you start
Make sure you have the exact hostname or record name to change and the IPv4 address supplied by the relevant technical provider. If you are not sure what an A record is, read the A record explanation first.
General steps to update an A record
- Log in to the service that manages DNS for the domain.
- Open the DNS records, DNS zone or DNS management area.
- Locate the correct A record by checking its type and hostname.
- Edit the record and replace only the destination value you have been instructed to change.
- Review the entry carefully and save it.
- Allow time for the DNS change to become visible across different networks.
If you cannot find the DNS area, see how to find your DNS settings.
Do not alter unrelated DNS records
DNS zones often contain records for email, verification, subdomains and other services. Do not delete or modify them because they appear unfamiliar.
Strong warning: change only the record you have been told to change. Never invent an IP address or copy one from another website.
What happens after I save the change?
The updated record may appear quickly for some visitors while other networks temporarily keep the previous value in cache. That is normal during a DNS update.
