Convert hostname to IP Address

[RBoy (www.rboyapps.com - Making SmartThings Easy!)]

When calling hubAction from a device code one needs to use IPAddress and ports. this is what I understood from here:

Any Documentation on "physicalgraph device HubAction"?

Nope. It’s easier than you think def sendRequest() { TRACE("sendRequest()") def httpRequest = [ method: settings.httpMethod, path: settings.httpResource, headers: [ HOST: state.networkAddr, Accept: "*/*", ] ] def hubAction = new physicalgraph.device.HubAction(httpRequest) sendHubCommand(hubAction) } where ‘state.networkAdd’ is IP:PORT in dotted notation.

so if the user enters a (public) hostname instead of an ipaddress when initializing the device, how does one convert it to an IPAddress. @urman looping you into the conversation incase you’ve any insight into this and why InetAddress doesn’t work with ST.
