1) We ran out of IPs, and need a new IP range.<br />
2) The rest you lost me on. My question (assuming I setup a new vlan on the router, a new DHCP scope for the new network. Does that mean that each request from old network to new network would have to go through the router?

Don't make subnet larger than the normal 254 Host networks you get with a 24bit mask. &nbsp;Ethernet looses efficiency around 250-300 hosts,...rolling back the mask by 1 bit will jump it to 510 hosts which is way to big to keep good performance.<br />

What is the best way to add more IPs for the internal network - without having to reconfigure all the existing computers?

DHCP Scope and re-assignment WS 2008R2

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.

Networking

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
