Example 2:IP address: 192.168.23.35 Subnet Mask: 255.255.255.0Network id:192.168.23.0 host Id:35 Iv. Subnet and CIDR By converting a regular subnet mask to binary, you will find that the subnet mask is contiguous binary 1 and continuous 0, where 1 of the subnet mask represents the network ID and the host ID of 0 in the subnet mask. For example, 255.255.0.0 is converted to binary 11111111 11111111 00000000

I was so happy to receive two CDs of Ubuntu7.10, each of which is 32-bit and 64-bit, sent by the Netherlands free mail. It took more than an hour to successfully install it on the old machine. Because the school IP address is bound to the MAC address, the old machine cannot obtain the

Born under the red flag long in the spring breeze, long soak in the crab society inside so over time there are some of the way of thinking of the crab, just for a while to do one. NET Web site access statistics system, by the way, how to "monitor" under each of the blogger's location, so there is now the figure shown in accordance with the message received by the IP address of the area where the message is,

With the increasing popularity of the Internet, the number of Internet users more and more, the number of visits to the major sites increased, especially many task sites or registration sites, in order to prevent malicious registration, will increase access, click, and so on a variety of restrictions, the most common is the IP limit. However, many users such as companies, schools, etc., in the same local area network users, the external

, and there is still a lot of free address space. If possible, use a continuous subnet. Although this is not important, it makes sense to select a continuous range of addresses and assign a specific subnet mask to these addresses. As will be highlighted in the next section, when discussing route aggregation, efficient IP Addr
