Changing IP addresses for multiple sites simultaneously allows server administrators and resellers to update domains in bulk rather than one at a time. This feature is particularly useful when transferring accounts between resellers or restructuring server resources. The process takes just a few clicks in your hosting control panel.
Why Change Multiple IP Addresses at Once
Bulk IP address changes save significant time when managing multiple domains. Common scenarios include transferring accounts between resellers, migrating domains to different servers, or reorganizing hosting infrastructure. Instead of updating each domain individually, you can select multiple accounts and change their IP addresses in a single operation.
This feature is especially valuable for resellers managing numerous client accounts or administrators overseeing large hosting environments. OBHost provides this functionality to streamline server management tasks.
How to Change Multiple Site IP Addresses
Follow these steps to update IP addresses for multiple domains simultaneously:
- Select the checkboxes next to the domains you want to update
- Click the button labeled Change IPs of Selected Accounts
- Choose the new IP address for each domain from the dropdown menu
- Click Change IPs to apply the changes
The system will process the updates and apply the new IP addresses to all selected accounts.
Important Considerations Before Changing IPs
DNS Propagation Delay: After changing IP addresses, DNS changes take time to propagate across the Internet. Nameservers worldwide need to update their records, which typically takes 24 to 48 hours. During this period, some visitors may experience temporary difficulty accessing websites as their DNS resolvers update.
Plan Accordingly: Schedule IP address changes during low-traffic periods when possible. Notify site owners in advance so they can inform their users about potential brief disruptions.
Verify Settings: Double-check that you've selected the correct new IP addresses for each domain before confirming the changes. Incorrect IP assignments can cause websites to become inaccessible.
What Happens After Changing IP Addresses
Once you complete the IP address change, the system updates DNS zone files and configuration files on the server. The domains will begin resolving to their new IP addresses, though full propagation depends on DNS caching across the Internet.
Monitor the affected domains after making changes to ensure they remain accessible. If issues arise, you can revert the IP addresses using the same bulk change feature.
Frequently Asked Questions
How long does it take for IP address changes to take effect?
The changes apply immediately on your server, but DNS propagation across the Internet typically takes 24 to 48 hours. During this time, different users may see different IP addresses depending on their DNS resolver's cache.
Will changing IP addresses cause downtime?
There is usually no complete downtime, but some visitors may temporarily experience difficulty accessing websites during DNS propagation. This happens because their DNS resolver still has the old IP address cached. The issue resolves automatically as DNS records update.
Can I change IP addresses back if something goes wrong?
Yes, you can use the same bulk IP address change feature to revert domains to their previous IP addresses. Simply select the affected domains and assign them back to the original IPs.
Do I need to update nameservers when changing IP addresses?
If you're only changing the IP address where sites are hosted, you typically don't need to update nameserver records. However, if you're moving to a completely different server with different nameservers, those will need updating at the domain registrar.
