IPs are masqueraded by default in Autopilot to use the node IP for egress traffic. which is just a fancy way of saying, the Pod traffic looks like it comes from the node's IP. This is handy when using non-RFC1918 ranges in GKE to avoid IP exhaustion, since your Node IP range is typically in RFC| William Denniss
GKE operates on a flat VPC structure. That means that every Node and Pod has an identity within your VPC, and their IPs are not re-used. This is convenient, as Pods are addressable within the VPC, but unless you create multiple VPCs to isolate resources, you can end up using a lot of IPs very quickl| William Denniss
Did you know that you can now add Pod IP ranges to GKE clusters? Pods use a lot of IPs, which in the past forced you to compromise. Do you allocate a lot of IPs to the cluster allowing for growth while reserving a big group of IPs, or do you allocate just a little to conserve IPs but risking the nee| William Denniss
