@@ -21,7 +21,7 @@ Note:
 Make sure node IPAM allocation is disabled in kube-controller-manager to avoid both controllers competing to assign CIDRs to nodes. To make sure its disabled, check and make sure kube-controller-manager is not started with `--allocate-node-cidrs` flag.
 
 ## Allocated subnet size
-By default, CCM allocates /24 subnet for ipv4 addresses and /112 for ipv6 addresses to nodes. For ipv6 cidr allocation using CCM, linodes should have ipv6 ranges configured on their interfaces. If one wants different subnet range, it can be configured by using `--node-cidr-mask-size-ipv4` and `--node-cidr-mask-size-ipv6` flags.
