29 subnet

🗓️ Published on October 27, 2025

The /29 subnet is a pretty important tool in IP networking because it helps you manage a small batch of IP addresses efficiently within a network segment. Getting the hang of it can really level up your networking skills and make it easier to set up networks the right way. In this guide, we'll walk through what the /29 subnet is all about, how it actually works, and how IPv4 and IPv6 compare.

Overview

A /29 subnet gives you eight IP addresses total, but only six of them are actually usable for your devices. It's really handy for small networks or when you're connecting just two points together where you don't need a ton of addresses. The other two addresses get reserved for the network itself and the broadcast address.

How It Works

So here's how a /29 subnet breaks down: the first address is your network address, the last one's the broadcast address, and everything in between gets assigned to your devices. Let's say you've got the subnet 192.168.1.0/29. Your usable IP addresses would be 192.168.1.1 through 192.168.1.6, while 192.168.1.0 is the network address and 192.168.1.7 is the broadcast address.

IPv4 vs IPv6

IPv4 addresses, like the ones you'd use in a /29 subnet, are still everywhere even though IPv6 has been growing. IPv6 was created to fix IPv4's biggest problem-we were literally running out of addresses. A /29 subnet works fine for smaller networks, but IPv6 gives you way more addresses to work with, which means better routing and more devices can connect. Making the switch to IPv6 helps your network scale better, and honestly, that's going to be important down the road.
