# Global Pools An IP Pool is a single configuration point for the assignment of IP addresses to clients. Basically, an IP pool is a group of IP addresses for use by a specific customer. Each customer pool (or pools) must have its own set of IPv4 addresses, which must not overlap with those of any other pool belonging to the same customer. You can allocate addresses from customer pools across multiple Layer 3 VPNs for a particular customer.
