Do Fiber Node have IPAddress

Hello,

I would like to know, if IPaddress is been assigned to FiberNode, by DNS Server located at MSO Head end. (is DNS Server will be available at head end or it is available at ISP) .

In case the Fiber Node have IPAddress, which MIB will expose that details, so that I can use that and check the status of FiberNode with periodic status Polling.

Also how does the IPAddress assigned to Cable Modem ?

Thanks is advance
