There are generally two ways to accomplish this: segment the devices (student devices in one subnet, teacher devices in another, admin in another, etc.) or increase the size of the subnet.<br><br>If you are using a /24 subnet (mask 255.255.255.0) you could change it to a /23 (mask 255.255.254.0). &nbsp;You have to be careful, though. &nbsp;Make sure you know which devices use static IPs as you'll need to change the mask on those.<br><br>You will get more broadcast traffic with the larger subnet approach. &nbsp;That may or may not be an issue for you.

<div>
the issue is will DHCP on the router give out both subnets to the clients automatically or will one subnet have to be all static and the other automatic. <br>&nbsp;<br><br>

<div>
actually i just found the answer online<br>It does not provide DHCP for the second subnet.&nbsp;

How to extend DHCP lan to another Subnet on Cisco RV042 Router

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).

DHCP

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
