Maximum number of devices permitted

Hi,

I have taken the basic 40$ Xfinity plan with a renting of a modem/router from Xfinity. I was wondering as to how many devices I could connect to the modem based on this plan.


Thanks

Re: Maximum number of devices permitted

253 devices max usually.  Depends on the DHCP server on the gateway/modem as to how big a pool it will route, and what you set it for.  3rd party gateways/firmware may let you handle more.

 

One IP address is assigned as the base lan IP (internal address).  It will look something like 192.168.0.1 or 192.168.1.1 on most of these. 

 

There is a pool of dynamic addresses that can then possibly passed out on.  Possibly from 192.168.0.2 to 192.168.0.254, but it might be set to far fewer address by default (perhaps 50 IP addresses from 192.168.0.2-192.168.0.51 or so.  

 

Most of the time, it's in the LAN configuration tab on your gateway, but I don't use Xfinity gear, and you didn't specify the model, so you'll have to look when you set it up.

 

If you really need to route a ton of devices, or collect per device statistics on everything,  use an internal DHCP server and router (linux/unix box with firewall, pfsense, opnSense, DD-WRT router.....whatever), and run everything through that.   It will work better.  Consumer gateways kind of struggle with routing large numbers of connected devices in the first place.
