feat: allow subnets in node ip allowlist

[derklaro]

Motivation

The current node ip allowlist is only able to handle static ip addresses, not subnets. This causes issues with subnet usage, for example, when running services in docker containers using a custom network.

Modification

Add support for subnets in the node ip allowlist. The allowlist accepts static ips or subnets, depending on the fact if the allowlist entry contains a / to delimit the ip from the subnet prefix length.

Result

The ip allowlist can now handle subnets alongside static ip addresses.
