Windows server 2003 custom dhcp options

The scope Description is not required. It is there in case we needed to provide a broader description of the scope. Specify an IP address range and subnet mask. For the Start IP address enter Finally, specify a subnet mask of Specifying the IP address range of a scope requires some knowledge of subnetting. Each scope in a DHCP server holds a pool of IP addresses to give out to clients, and the range of IP addresses must be within the allowed range of the subnet that you specify on the subnet mask field.

For simplicity we entered a classful, class C IP address range from Notice that the range encompasses the IP address of our server, the DNS servers and the default gateway, meaning that the DHCP server could potentially assign a client an IP address that is already in use! Do not worry -- we will take care of that later.

Specify IP addresses to exclude from assignment. For the Start IP address , enter Certain network devices, such as servers, will need statically configured IP addresses. The IP addresses may sometimes be within the range of IP addresses defined for a scope.

We have the opportunity here to define those IP addresses that are to be excluded. We specified IP addresses Specify the lease duration for the scope. Verify that Days is 8 and click Next. The lease duration is how long clients should keep their IP addresses before having to renew them. There are a few considerations at this point. If a short lease duration is configured, clients will be renewing their IP addresses more frequently.

The result will be additional network traffic and additional strain on the DHCP server. On the other hand if a long lease duration is configured, IP addresses previously obtained by decommissioned clients would remain leased and unavailable to future clients until the leases either expire or are manually deleted. Additionally if network changes occur, such as the implementation of a new DNS server, those clients would not receive those updates until their leases expire or the computers are restarted.

In an environment where computers are often moved and replaced, such as a wireless network, you would want to specify a short duration since a new wireless client could roam within range at any time. These are the other settings that help clients communicate on the network. Specify the router IP address. Improve this answer. Zoredache Zoredache k 39 39 gold badges silver badges bronze badges.
