// Retrieves version information for an IPAM prefix list resolver.
//
// Each version is a snapshot of what CIDRs matched your rules at that moment in
// time. The version number increments every time the CIDR list changes due to
// infrastructure changes.
//
// Version example:
//
// Initial State (Version 1)
//
// Production environment:
//
//   - vpc-prod-web (10.1.0.0/16) - tagged env=prod
//
//   - vpc-prod-db (10.2.0.0/16) - tagged env=prod
//
// Resolver rule: Include all VPCs tagged env=prod
//
// Version 1 CIDRs: 10.1.0.0/16, 10.2.0.0/16
//
// Infrastructure Change (Version 2)
//
// New VPC added:
//
//   - vpc-prod-api (10.3.0.0/16) - tagged env=prod
//
// IPAM automatically detects the change and creates a new version.
//
// Version 2 CIDRs: 10.1.0.0/16, 10.2.0.0/16, 10.3.0.0/16
