Abstract
A first router obtains a first network address of a first local area network (LAN) implemented by a second router and a first subnet mask associated with the first LAN. The first router causes the establishment of a secure communications channel with the second router. The first router determines that a computing device seeks to join the first LAN. The first router obtains an internet protocol (IP) address that has a same network address as the first network address and sends, to the computing device, the IP address and the first subnet mask for use by the computing device.
