 ### API Loadbalancing
-ProxLB supports API loadbalancing, where one or more host objects can be defined as a list. This ensures, that you can even operator ProxLB without further changes when one or more nodes are offline or in a maintenance. When defining multiple hosts, the first reachable one will be picked.
+ProxLB supports API loadbalancing, where one or more host objects can be defined as a list. This ensures, that you can even operator ProxLB without further changes when one or more nodes are offline or in a maintenance. When defining multiple hosts, the first reachable one will be picked. You can speficy custom ports in the list. There are 4 ways of defining hosts with ports:
+1. Hostname of IPv4 without port (in this case the default 8006 will be used)
+2. Hostname or IPv4 with port
+3. IPv6 in brackets with optional port
+4. IPv6 without brackets, in this case the port is assumed after last colon
