Adding or editing IP addresses

Applies To: Windows Server 2008

You can use the following options to specify which IP addresses or subnets are allowed or denied access to your server.

Element Name Description

Single computer

Select this option to add the IP address of a single computer to the list.

IP Address

Type the unique 32-bit address used to identify the computer; for example, 208.147.66.20.

Group of computers

Select this option to add a range of computers based on the subnet address and subnet mask.

Subnet address

Type the unique 32-bit address used to identify a client computer in the group; for example, 208.147.66.20.

Subnet mask

Type the 32-bit number used to evaluate the subnet address and produce a range of IP addresses for the access list; for example, 255.255.255.0.

Single computer

Select this option to add the IP address of a single computer to the list.

Note

If an IP address is specified in both the Allow and Deny lists, the Deny list takes precedence. To set a range of addresses, each bit in the mask is compared to the corresponding bit in the IP address. Where the value in the mask is 1, the corresponding bit in the IP address is included in the list. Where the value in the mask is 0, any value is acceptable. In the example, the IP address in the list is 208.147.66.20 and the mask is 255.255.255.0; thus all IP addresses from 208.147.66.0 to 208.147.66.255 are included in the list. If the mask were 255.255.255.128, all IP addresses from 208.147.66.128 to 208.147.66.255 would be included in the list.

Note

Windows Media Services is Internet Protocol version 6 (IPv6) enabled. IPv6 is the newest version of the Internet Protocol and was designed to accommodate the rapidly increasing demand for unique IP addresses. IPv6 increases the IP address size from 32 bits to 128 bits to support more levels of addressing hierarchy and a much greater number of addressable nodes. Not all networks are configured to use IPv6, so Windows Media Services will automatically use it when it is available.

Note

Properties for this plug-in cannot be configured in Windows Media Services Administrator for the Web.
