kube-router assigning ClusterIPs outside of default subnet

QUESTION

kube-router assigning ClusterIPs outside of default subnet

Asked 2021-Jan-18 at 12:44

I have in my home lab a default installation of Kubernetes with kube-router as the network provider. kube-router is, as default, set as the service proxy. I have not set an explicit service-cluster-ip-network in my kube-controller-manager, so kube-router should be assigning service cluster IPs only within the default 10.96.x.x/16 subnet. However, I am regularly getting service cluster IPs anywhere within the larger 10.x.x.x./8 subnet. I am at a loss where/why it's not remaining within 10.96.x.x. Ideas? Thanks!

TL;DR

Your Kubernetes cluster is behaving correctly.

By default (if not specified otherwise) using kubeadm to provision your cluster, the --service-cidr is set to 10.96.0.0/12.

ClusterIP address like 10.110.15.13 would be included in the above mentioned network (10.96.0.0/12).

I've provided more explanation below:

Subnetting

If you use one of the available online IP calculators you will be seeing exact same situation like the one included below:

CIDR 10.96.0.0/12 Subnet mask 255.240.0.0 Network address (first) 10.96.0.0 Broadcast address (last) 10.111.255.255 First useable address 10.96.0.1 Last useable address 10.111.255.254 Number of hosts allocatable 1048574

By above diagram you can see that the Service IP range would be following:
