Anyone involved in website hosting eventually faces the task of migrating websites from one server to another. In such cases, the A records for multiple domain names need to be updated. This task can be accomplished using the Bulk Changes feature.
To add the records, do the following:
1. Open the DNS-master editor and select Bulk Changes from the menu.

2. Select the A record type, use the IP address filter, and specify the new IP address. Click Apply (Применить).

3. Upload (publish) the zone to the DNS servers.

Changes will take effect within 1–2 minutes.
