Routers are able to deliver data to the right subnets, which generally are still corresponding to the network segment. Numbers game. If you read the articles about IP addresses, you'll learn that the numbers break down into 1) the network ID and 2) the host ID. So where does this subnet ID come from?

The router is configured with a subnet on each of its link. It uses this configuration to build its routing table (these are called connected routes). The router looks up its routing table to find that it needs to use LAN 2 to reach any host in the 20.0.0.0/8 network. The router then uses ARP to find the MAC for Host B … How to get into a modem/router that is in bridge mode #1 Both routers can not be in the same subnet (see option two, as I explained what that means.) #2 Setup a Static WAN IP of the RJ-45 router so that is in the same subnet as the device that is in bridge mode. #3 Based upon what you are trying to do, assuming the same subnets setting before you must use: IP Address: 192.168.1.2 Can't reach cable modem interface after changing LAN subnet Sep 03, 2019

A subnet mask is like an IP address, but for only internal usage within a network. Routers use subnet masks to route data packets to the right place. Subnet masks are not indicated within data packets traversing the Internet — those packets only indicate the destination IP address, which a router will match with a subnet.

Understanding TCP/IP addressing and subnetting basics Dec 19, 2019 What is a Subnet Mask Address and How to Find Yours So, a subnet is used to enable a collection of devices to connect to the Internet with a single IP address through the use of a router (like you have at home or in your office) and in this way a lot more than three billion devices can have access to the Internet. This is what was explained above with 1 public address for your whole network.
