subnet mask on router

address cannot begin with the decimal "127", which is the number 127 in the class address. 0. 0. 1 to 127. 255. 255. 255 for loop testing, such as: 127.0.0.1 can represent the native IP address, with "http://127.0.0.1" can test the configured Web server in this computer. The first 8-bit group of the network ID cannot be completely set to "0", and all "0" represents the local network. Second, private IP address range Private IP address is a reserved IP address. Only used in LAN, not in inteU

address of a network to another network. For example, network A and network B, network A's IP address range is "192.168.1.1~192." 168.1.254 ", the subnet mask is 255.255.255.0; The IP address range for Network B is" 192.168.2.1~192.168.2.254 "and the subnet mask is 255.255.255.0. In the absence of a

address range is "192.168.1.1~192." 168.1.254 ", the subnet mask is 255.255.255.0; The IP address range for Network B is" 192.168.2.1~192.168.2.254 "and the subnet mask is 255.255.255.0. In the absence of a router, TCP/IP communication between the two networks is not possib

The most direct role of the subnet mask is to determine whether the IP address is within the same network segment as another IP address. Here is a simple look at the basic configuration of IP on a computer IP Address: 192.168.0.5 Subnet Mask: 255.255.255.0 Default gateway: 192.168.0.1 Example above, IP address,

? A gateway is essentially an IP address from a network to another network. For example, if Network A and Network B exist, the IP address range of Network A is "192.168.1.1 ~ 192. 168.1.254 ", The subnet mask is 255.255.255.0, And the IP address range of Network B is" 192.168.2.1 ~ 192.168.2.254 ", and the subnet mask

addressing decision by identifying the network number and subnet number of the destination address. The host part of the IP address is not involved in the routing addressing operation of the router, only an interface that uniquely identifies a network device in a CIDR block. Originally, if only the primary class addresses A, B, and C are used in the network system, and the primary class addresses are not d

To configure the default gateway, you

The subnet mask (subnet mask) is also called the netmask, address mask, and subnet mask, which is used to indicate which bits of an IP address identify the host's

255.255.255.255: Broadcast address. IP address 0.0.0.0: Represents any network. The host bit is all 1: Represents the broadcast address of the network segment, that is, all the hosts of the network segment. The host bit is all 0: represents the network address of the network.0x5.ip subnetting A. IP address of the subnet is not divided by its problemsProblem with non-partitioned IP address: address wasted , broadcast domain too largeB. The IP address

Just change the first three digits of the IP address and the last digit of the gateway to an unused IP address, I have never understood what the subnet
