I have a problem. On my network I am running out of IP numbers on the subnet. Completely consumer level items are being used. I am planning to expand my garage and add a few more items that will put me over the subnet limit.

What are my options as I want all devices to be able to communicate with eachother.

Also can anyone explain why we even have this limitation in this day and age?

Just fucking change your DHCP scope and update the static addresses on the devices to the new subnet.

How many fucking devices do you have?

tell me more about the sandwich OP

Almost 255.

Assuming you're using the network 192.168.0.0/24:
First host: 192.168.0.1
Last host: 192.168.0.254
BC: 192.168.0.255
NM: 255.255.255.0
Max hosts: 254

Simplest Solution:
Change subnet mask on all devices to 255.255.0.0
First host: 192.168.0.1
Last host: 192.168.255.254
BC: 192.168.255.255
Maximum hosts: 65,534

ffs

Wondering why 255.255.255.0 is the default mask virtually everywhere. Why don't we use a higher/larger class by default even for home networks? Higher overhead?

I don't know the answer to that. For private IPv4 networks you could have:
10.0.0.0/8 (255.0.0.0)
Broadcast: 10.255.255.255
HostMin: 10.0.0.1
HostMax: 10.255.255.254
TTL Hosts: 16,777,214

And then with IPv6.....well.....it only goes up. On a LAN especially, it's quicker to scan the entire network for devices if the network is limited. It likely takes less than 10 seconds to scan you entire 255.255.255.0 network. It takes much longer to scan a network as that network gets bigger.

IPv6 doesn't have this problem.

>Running out of IP addresses at home
>Has no idea how networks work
Nigga, whatchu doin'?
Just how many porn devices do you need in the house?

Reconfigure your DHCP server and any devices with a static IP with a subnet mask which dedicates more bits to the network part of the address, this isn't a problem at all.

What the fuck? Are you running a bunch of IP cams, smart plugs, and chromecasts on the same LAN? Time to look into VLANs and learn some proper, basic network topology as well.
>Completely consumer level items are being used.
jfc, RIP your current network bandwidth. Probably took you an hour just to load this thread.
IPv4 doesn't have this problem, either. OP just hooked everything together like a total mong without any foresight whatsoever.

All the porn in all the rooms.

What is BC and NM?

255 smart dildos to jam into every hole.

I'm more interested in that sandwich desu

never seen it abbreviated as such but "bc" looks to mean broadcast
nm as network mask

Would that have to be done from the devices? Can we not just do it from the router?

>not knowing shit about networking and subnet masks
>/24 -> /16 problem solved
is this the state of /g?

I just want that tasty looking sammich

but also please elaborate on the devices you have, even if I networked everything I've ever hoarded I'd barely hit 50 addresses

Find a better IPS that gives you an IPv6 ip so you can have IPv6 private network..

I'm really having a hard time figuring out how you have 255 devices that need an IP at your home.

Because most people don't have more than 200 network devices in their homes.

probably quicker for scanning tools to search with a smaller scope

Wifi outlets and wifi light switches are a big chunk.

Do you have 10 outlets per room?

8

How do you have over 200 devices connected to your network and not know how to solve this problem? That must be one ugly fucking mess of a network that's begging to be turned into a botnet.

Just out of curiosity, OP, what's your external IP? :^)

No, change it to /23 not /16, you fucking mong

That doesn't even begin to sound like a possibility. I live in a fairly spacious 3 story house and I can't see myself even breaking 100 if every light and outlet needed their own IP.

because large broadcast domains are bad
t. network architect

Decrease DHCP lease time

God damn it, are you niggers even trying?

All wifi.

Literally just make another subdomain to put your IoT in (and block it from accessing the Internet).

Then how would you consider tell them?

Wtf did I just voice to text?
I meant to say "How do you control them?".

jesus christ learn how a firewall/router works

Did you not read the first post asking for help learning the solution? Maybe you missed it. The first post is often hard to see.

Preferably, don't.
There's nothing more cringe.

Those smart rocks (devices) are connected to a network. When smart rocks are interconnected, they are ruled by network nodes (routers). A router will forward/reject/dnat/snat/trap a rock when said rock need to talk to another rock.

Because having 200+ devices contesting IP addresses will not cause any issues right?

>Because having 200+ devices contesting IP addresses will not cause any issues right?
Right, it won't. But lease time won't solve anything if the devices are always on anyway.

Why would you not assign IP numbers to devices?

This is the best answer.

You know, you can separate subnets

I know that. People like OP will probably be told to use something like 255.0.0.0 or 255.255.0.0 for their whole LAN instead of doing that, then breaking it down into something manageable, like /24 blocks. Then they'll come back asking why their network goes out when a thousand or so devices simultaneously need an IP address or need the MAC address of the default gateway.

OP here. What?

yes that also works
We could likely argue and talk about "what's the ideal netmask" all day long. I picked /16 primarily to highlight the magnitude in address space that simply changing the address makes.

I overlooked this, totally true. At the same time though, OP and this thread in general are discussing consumer LANs. Realistically you (shouldn't) have negative ramifications to the degree that is being discussed in this thread, and it's also unlikely that the average consumer is going to invest in multiple routers and deal with the administration that demands.

ugh you're telling me, i need that cunt in my mouth yesterday

I need every single delicious inch of that bad boy inside me. Right now.
