how to find subnet mask from ip address

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:

two computers are in the same network 192.168.0.0, so can pass, and 2, 3 cases two computers in different networks, so it does not pass.Here is a conclusion: the computer with a direct connection to the network cable or through the hub (hub) or the ordinary switch between the computer to be able to communicate with each other, the computer must be on the same network, that is, their network address must be the same, And the host

) used by the NetWare network. Gateways are also known as IP routers.What is the default gateway? The default gateway means that if a host cannot find an available gateway, it sends the packet to the default designated gateway, which handles the packet. The gateway used by the host is now generally referred to as the default gateway.DNS server:DNSRefers to the domain name server. InThe domain name on the in

three subnets, one of which has 100 hosts, and two hosts for the rest of the seven subnets. We know that a class C address has 254 available addresses, so how do you choose a subnet mask? From the table above, we find that this problem cannot be solved when we use a subnet

, 255.255.255.255.192. The computer cannot communicate normally.Figure 3In 1st cases, the two computers are in the same network as 192.168.0.0, so the two computers are in different networks.The following is a conclusion: computers that are directly connected by a network cable, or computers that are indirectly connected through a hub or common switch, must be in the same network, that is to say, they must have the same network address and the host

A few words to master subnet mask, IP address, host number, network number, network address, broadcast address1, 191.172.16.10.33/27 in the/27 that is, the subnet mask is 255.255.255.22

The IP address is composed of four digits. Here, let's take a look at three common IP addresses.Class a ip segments 0.0.0.0 to 127.255.255.255Class B IP segments 128.0.0.0 to 191.255.255.255C-type IP segments 192.0.0.0 to 223.255.

Turn from: http://hi.baidu.com/ww2000e/item/98f7b9f6d396d5b430c1994f First of all, we look at a CCNA test common problem: The IP address of a host is 202.112.14.137, the mask is 255.255.255.224, requires computing the network address and broadcast address of the host networ

I don't need to analyze it professionally. I use dummies to answer questions. This is a simulated question. Use this question as an example. URL type: Of course, it is Class B. Convert the IP address and subnet mask to binary, and then perform operations on them. 145.189.24.3 10010001 10111101 00011000 00000011
