In this type of topology, you’ll find that there’s a path from every machine to every other one in the network. That’s a lot of connections—in fact, the mesh topology wins the prize for “most physical connections per device”! You won’t find it used in LANs very often, if ever, these days, but you will find a modified version of it known as a hybrid mesh used in a restrained manner on WANs, including the Internet.
Often, hybrid mesh topology networks will have quite a few connections between certain places to create redundancy (backup). And other types of topologies can sometimes be found in the mix, too, which is another reason it’s dubbed hybrid. Just remember that it isn’t a full-on mesh topology if there isn’t a connection between all devices in the network. And understand that it’s fairly complicated.
