PS: found a good article on the Internet, carried over, in case you can't find it later. At the same time the individual made a simple change. IP address, subnet mask, default gateway, what does DNS server mean?(a) Problem analysis001. Q: IP address,

changes all the numbers at the top to 0, No matter what number it is. if you convert the result back to decimal, you will get10.20.232.0This network ID. During the course of teaching the subnet division, I always felt uncomfortable: the students did not have access to simple methods to bypass and perform binary conversions during operations. I even saw it workers in related fields use this slow and troublesome method to convert to binary values, and

NETMASKFFFFFFC0 = ff.ff.ff.c0=255.255.255.192 binary is 11111111.11111111.11111111.11000000Another common method used to denote netmask is a two-bit number, such as "26", which is calculated as follows:11111111.11111111.11111111.11000000=> (1+1+1+1+1+1+1+1) + (1+1+1+1+1+1+1+1) + (1+1+1+1+1+1+1+1) + (1+1+0+0+0+0+0+0 ) =8+8+8+2=26For a given network IP address (171.197.26.137) and netmask (255.255.255.192),

In order to learn more about the TCP/IP protocol, I have read a lot of relevant information recently and collected the following records for later use and convenience: What does IP address, subnet mask, default gateway, and DNS server mean?

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 mas

Angry IP subnet obtains the IP address of the device. This software is used to scan the IP addresses of hosts in a certain CIDR block. Through usage discovery, the principle is to quickly ping each ip

IntroductionThis article describes what the IP address and its function and IP address composition, IP address classification, IP subnet par

The following small series for everyone to bring an article WinForm C # get the MAC address, IP address, subnet mask, the default gateway instance. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's take a look at it with a little knitting. 1. Add an assembly 2. Introd

PrefaceThis document is simply a logical algorithm, and how to compute network bits, host bits, and broadcast addresses in the case of known IP addresses and subnet masks. All steps are far from the most primitive binary way, the direct hit principle, please read carefully.1.

the need to request a purchase.Subnet Mask:The subnet mask is not an address, it is used to determine which part of an IP address is the network ID, which part is the host ID, the portion of a continuous 1 represents the network ID, and a continuous portion of 0 represents the host ID. For example, the first 24 bits o

What is an IP addressThe so-called IP address is a 32bit address assigned to each host connected to the Internet. In accordance with the TCP/IP protocol, IPs are represented by binary, each IP
