The subnet mask cannot exist alone, it must be used in conjunction with an IP address. The subnet mask has only one function, which is to divide an IP address into two parts: network address and host address.The subnet mask settin

As for subnet division, the subnet mask is odd. 1.0.1.0 -- 1.0.3.255 Fujian Telecom converts the subnet mask to an IP segment 1.0.1.0/24--1.0.2.0/23, if two IP addresses are replaced by binary IP addresses in a general way, or the budget is 0001.00000000.00000001.00, the

/***************************************************************************** * Subnet mask, mask length relationship * Statement: * When we operate the Linux system, we often see that we can use the subnet mask, mask length to r

The network does not pass, this is the most network problem table image, but if you can access me, but I can not access you, this problem is more troublesome. This article is the author in the actual combat in a subnet mask caused by the fault summary. The network is a phenomenon that often occurs, encounter this phenomenon, I believe many people will focus on network cable, NIC driver, network card parame

migration and so on, it will cause great trouble to the network management, so it is not recommended.In Windows 9x, the way to set the default gateway is to right-click on "My Network Places", click "Properties" in the pop-up menu, select "TCP/IP protocol" in the Net Properties dialog box, click on "Properties", and in the "Default Gateway" tab, fill in the IP address of the new default gateway.It is important to note that the default gateway must be the IP address in the computer's own network

IP addresses, subnet masks, and gateways in network management are the basic knowledge that each network administrator must master. Only by mastering them can you really understand the TCP/IP protocol settings. The following describes what a subnet mask is.To understand what the subnet

Subnet Mask:What is a subnet mask subnet mask cannot exist alone,It must be used in conjunction with an IP address. The subnet mask has only one effect,is to divide an IP address into t

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

Subnet mask (Subnet masks): The subnet mask is used to identify which part of the IP address is a network address. Which part is the host address, there are 1 and 0 components, long 32 bits, all 1 of bits represent the network number. Not all networks require subnets, so th

Summary: Class A, B, C is actually the concept of address block, the so-called application of a class C address, refers to the application of a Class C address block. C class Address block of specific IP address of this class C address block, of course, also belong to Class C address classes. A subnet mask is a subnet, such as a number of 200多万个 address blocks th

principle is very simple, using the ARP protocol to broadcast their own IP address to the network, if the response there is an IP conflict, this function in the tcp/ The first volume of the IP protocol ARP protocol chapter is described in detail. This first uses the ping command to probe the set IP address, and then in the ARP cache to find out if there are valid records, if any, there is an IP conflict. There is no need to care whether the ping command succeeds, whether or not it succeeds, as
