1 subnet
A subdivision of an Internet Protocol (IP) network. Each subnet has its own unique subnetted network ID. -
2 subnet mask
"A 32-bit value that enables the recipient of Internet Protocol version 4 (IPv4) packets to distinguish the network ID and host ID portions of the IPv4 address. Typically, subnet masks use the format 255.x.x.x. IPv6 uses network prefix notations rather than subnet masks." -
3 default subnet mask
A subnet mask that is used on an Internet Protocol version 4 (IPv4) class-based network. The subnet mask for Class A is 255.0.0.0. The subnet mask for Class B is 255.255.0.0. The subnet mask for Class C is 255.255.255.0. -
4 custom subnet mask
A subnet mask that is not based on the Internet address classes. Custom subnet masks are commonly used when subnetting. -
5 screened subnet
One or more computers that have a connection to the Internet through an external screening router and a connection to the internal network through an interior screening router. Computers that are linked to the perimeter network have limited access to both the Internet and the internal network. This architecture is convenient if multiple hosts require direct Internet access.شبكة فرعية مراقَبة -
6 superscope
"An administrative grouping feature that supports a DHCP server's ability to use more than scope for each physical interface and subnet. Superscopes are useful under the following conditions: If more DHCP clients must be added to a network than were originally planned, if an Internet Protocol (IP) network is renumbered, or if two or more DHCP servers are configured to provide scope redundancy and fault-tolerant design DHCP service for a single subnet. Each superscope can contain one or more member scopes (also known as ""child scopes"")." -
7 Automatic Private IP Addressing
"A TCP/IP feature in WindowsXP and Windows Server2003 that automatically configures a unique IP address from the range 169.254.0.1 through 169.254.255.254 with a subnet mask of 255.255.0.0 when the TCP/IP protocol is configured for dynamic addressing and a DHCP server is not available. The APIPA range of IP addresses is reserved by the Internet Assigned Numbers Authority (IANA) for use on a single subnet, and IP addresses within this range are not used on the Internet."English-Arabic terms dictionary > Automatic Private IP Addressing

8 APIPA
"A TCP/IP feature in WindowsXP and Windows Server2003 that automatically configures a unique IP address from the range 169.254.0.1 through 169.254.255.254 with a subnet mask of 255.255.0.0 when the TCP/IP protocol is configured for dynamic addressing and a DHCP server is not available. The APIPA range of IP addresses is reserved by the Internet Assigned Numbers Authority (IANA) for use on a single subnet, and IP addresses within this range are not used on the Internet."
