Hey everyone,

Quick question—can someone break down how many ips you actually get with a /29? I’ve seen different answers and it’s kinda confusing.

Like, I know the /29 gives you a block, but how many are *usable* after network and broadcast? Is it 6 or 8 total?

Just trying to set up a small network and don’t wanna mess this up lol.

Thanks in advance!

(Also, if anyone’s got a simple way to calculate /29 how many ips, that’d be awesome.)
Ah, the classic /29 how many ips question! You’re right, it’s 6 usable IPs. The /29 gives you 8 total, but the first is the network address and the last is the broadcast, so you’re left with 6 for hosts.

If you’re setting up a small network, that should be plenty. For quick calculations, I always use this site: [IP Calculator](https://www.calculator.com). Just punch in /29 and it breaks it down for you.

Hope that helps!
Wait, isn’t it 5 usable IPs? I swear I read somewhere that one’s reserved for the gateway too. Or does that depend on the setup?

For /29 how many ips, most folks say 6, but I’ve seen debates. Maybe someone can clarify if the gateway thing is a hard rule or just a common practice.

Either way, good luck with your small network!
Yo, /29 gives you 8 IPs total, but yeah, only 6 are usable for devices. Network and broadcast eat up the first and last.

If you’re confused about /29 how many ips, just remember: subtract 2 from the total. Works for most subnet sizes.

Also, if you’re lazy like me, just google “subnet calculator” and let the tools do the math.
For a /29, you get 8 IPs, but only 6 are usable—network and broadcast take the other two.

If you’re wondering about /29 how many ips are actually assignable, it’s always total minus 2. Some folks overcomplicate it, but it’s pretty straightforward once you get the hang of it.

Pro tip: Write it down somewhere so you don’t have to google it every time lol.
It’s 6 usable IPs in a /29. The confusion usually comes from forgetting about the network and broadcast addresses.

If you need a simple way to calculate /29 how many ips, try this: 2^(32-29) = 8 total, minus 2 = 6 usable.

Or just use a subnet calculator—way easier than doing the math in your head.
Thanks everyone! This clears up the /29 how many ips confusion big time. I’ll go with 6 usable then.

Also, that subnet calculator site is a lifesaver—no more guessing for me lol.

Quick follow-up: Does anyone know if the gateway *has* to be one of those 6, or can it be outside the /29? Just curious.
Honestly, the /29 how many ips thing trips everyone up at first. It’s 6 usable, 8 total.

The first IP is the network, the last is broadcast, and the rest are yours to play with.

If you’re setting up a small network, 6 should be enough unless you’re going wild with devices.
Yep, 6 usable IPs in a /29. The whole “/29 how many ips” thing is confusing because people forget about the reserved addresses.

For quick math, remember: /29 = 8 total, minus 2 = 6 usable.

If you’re visual, draw it out—helps a ton!
