{{Function
|name=rednet.host
|args={{type|string}} protocol, {{type|string}} hostname
|returns=Nothing
|api=rednet
|addon=ComputerCraft
|desc=Introduced by ComputerCraft 1.6, registers the system as "hosting" the desired [[Rednet (API)#Protocols|protocol]] under the specified name. If a [[rednet.lookup|rednet lookup]] is performed for that protocol (and maybe name) on the same network, the registered system will automatically respond via a [[rednet.run|background process]], hence providing the system performing the lookup with its ID number.<br><br>

Multiple computers may not register themselves on the same network as having the same names against the same protocols, and the title "localhost" is specifically reserved. They may, however, share names as long as their hosted protocols are different, or if they only join a given network after "registering" themselves before doing so (eg while offline or part of a different network).<br><br>

|examples=
{{Example
|desc=Registers the system as using the protocol "futonFolderComs" under the hostname "futonFolderServer". It'll respond to lookup requests (such as the example code for [[rednet.lookup|rednet.lookup()]]) until such time as rednet is closed, the name is unregistered (via [[rednet.unhost|rednet.unhost()]]), or the system is rebooted.
|code= rednet.open("top")
 
 rednet.host("futonFolderComs","futonFolderServer")
