When the system-assigned IP addresses are insufficient, you can apply for a public IP range in the console for Internet tunnel to meet your business requirements. This document describes how to apply for and manage public IP ranges.
Public IP Range Lifecycle
1. Apply for a public IP range: after your application is submitted in the console, a public IP range will be automatically assigned. The status of this public IP range will become “In use”.
2. A public IP range in use can be split or disabled.
Split an IP range: applicable to the scenario requiring a refined IP range. The public IP range is still in use.
4. Recover a public IP range: a public IP range that has been released in the last eight days can be recovered, which will be reassigned and resumed the “In use” status.
range will be automatically bound to the Internet tunnels in the same region.
1. Choose Internet Tunnels > Public IP Range on the left sidebar.
2. Select a region at the top of the page and click Apply.
