using RDM but dont know home IP

[RidleyJ329]

im away from home and left a program running on my computer but i recently flashed my phone which naturally reset everything. i forgot to reprogram my IP before leaving the house. its nothing urgent but i just wanted to check the status of the program so my question to you guys is is there anyway that i can locate the ip address of my home computer while im not sitting right in front of it? if not its no big deal i just figured it never hutrs to ask. if it matters im using mightys reborn rom.
