Alibabacloud.com offers a wide variety of articles about how to determine subnet mask, easily find your how to determine subnet mask information here online.
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

Python: a simple method for converting the subnet mask and a python Subnet Mask This article describes how to convert the subnet mask in Python. We will share this with you for your reference. The details are as follows: Here, t
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

to access content in Internet networks. A subsidiary's network is unable to ping the company's network, mainly because of the subsidiary's subnet mask parameter settings caused by error. We know that the host before sending the Internet request, often will first determine whether the target host is in the local subnet

Transferred from: http://baike.baidu.com/view/65511.htm Http://baike.baidu.com/view/878.htm The IP address is the network number and host number to represent the host on the network, only in a network number under the computer can be "direct" interoperability, different network number of the computer through the gateway to exchange. But such a division does not seem very flexible in some cases. For this reason, the IP network is also allowed to be partitioned into smaller networks called subnet
sends an Internet request to the local gateway. In this case, the 202.102.11.87 host of Company A can PING the server of the company. Once the network mask address of Company A is changed to 255.255.255.0, the local host considers that the address 202.102.11.87 and 202.102.11.2 are in the same network segment, therefore, the local host directly sends the Internet request to the target host instead of forwarding it to the local gateway. In fact, there
In TCP/IP, subnet masks are used to determine whether hosts on the network are in the same network segment. In A large network, the subnet masks of class a are 255.0.0.0, The subnet masks of class B is 255.255.0.0, And the SUBNET MASKS of CLASS C is 255.255.255.0. Assume tha
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
a router, TCP/IP communication between the two networks is not possible, even if the two network connections on the same switch (or hub), the TCP/IP protocol will determine the subnet mask (255.255.255.0) on the two network hosts in a different network. To achieve communication between the two networks, you must pass through the gateway. If the host in Network a
