subnet mask calc

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

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

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

As we all know, IP is made up of four numbers, here, let's first look at the Class 3 commonly used IPClass A IP segment 0.0.0.0 to 127.255.255.255Class B IP segment 128.0.0.0 to 191.255.255.255Class C IP segment 192.0.0.0 to 223.255.255.255　　The default subnet mask assigned by XP is only 255 or 0 per segmentClass A default subnet

You must know something about the IP address, right? We know that the TCP/IP protocol that is widely used in the Internet is to differentiate between different hosts by using IPs. If you've ever had a TCP/IP protocol set up, then you're bound to encounter the term subnet mask (Subnet mask), so do you know what a
