Maximum number of DHCP Clients?

Question

What is the most possible maximum number of DHCP Clients on any Router/Switch/HUB anything?

Answer 1

By default, there is no limit to the number of DHCP local server or DHCP relay clients allowed on an interface. However, you can override the default setting and specify the maximum number of clients allowed per interface, in the range 1 to 500,000. When the number of clients on the interface reaches the specified limit, no additional DHCP Discover PDUs are accepted. When the number of clients subsequently drops below the limit, new clients are again accepted.



To configure the maximum number of DHCP clients allowed per interface:



1. Specify that you want to configure override options.

* For DHCP local server:



[edit system services dhcp-local-server]

user@host# edit overrides



* For DHCP relay agent:



[edit forwarding-options dhcp-relay]

user@host# edit overrides



2. Configure the maximum number of clients allowed per interface. (DHCP local server and DHCP relay agent both support the interface-client-limit statement.)



[edit system services dhcp-local-server overrides]

user@host# set interface-client-limit number

Answer 2

It's specific to the router.



Switches and hubs cannot act as a DHCP server unless they're "inside" a router.

Answer 3

You typically use a static ip address for printers, servers, routers, gateways...etc... so considering a typical ip Version 4 scheme...there are what? 255 available addresses in your range, 1 and 255 are typically your nw and gateway...so a minimum of 253 available to be leased through DHCP minus what you have used as static. It would be much more if you were using IPv6 and this isnt including possible subnets. We would need more information to answer this question...

Answer 4

IPv4 isn't restricted to 253 address, because it's not restricted to just /24 subnets. To use, for example, 10.0.0.0 as the network and 255.0.0.0 as the default, classful subnet mask, you could assign all addresses from 10.0.0.1 to 10.255.255.254. So the literal answer, with the smallest legal network mask beyond supernetted CIDR summaries, would be 2^24 - 2, or 16777214.

Answer 5

You should be able to connect up to 253 devices/computers to the router. (Number is 255, but first address will be used by router itself and your computer will use the second one).

Answer 6

it have a pool of 252 ip addresses....
