. DNS rules about domain names are similar to the express systems in our lives, using hierarchical address structures. Express delivery system to send someone mail items, the address may be: China, Guangdong Province, Guangzhou City, Fanyu District, Zhongshan West Road, No. 12th XXX. And a domain name looks like this groups.google.com (why not com.google.groups?) I guess it might have something to do with the foreigner's habit of writing an address.For the Internet, the top level of the domain n

MAC address and IP address are global (global distribution), but IP addresses are layered and routable.The IP address is distributed progressively by ICANN and China is cnnic.Each interface of a host or router can be configured with one or more IP addresses.2.

DNS rules about domain names are similar to the express systems in our lives, using hierarchical address structures.

The IP address is a four segment 8-bit binary separated by three decimal points, divided into 5 classes according to the size of the first field:Class A: The first field is 0, the range is: 0000 0001--0111 1111, that is, the first field of the 1-127;a class is the network number, the third segment is the host number, the number of hosts can accommodate 2^24-2. The host bit is 0 for the network address, and the host bit is 1 for the broadcast address.Class B: The first field starts with 10, the r
is no. the IP address is allocated by ICANN. your data packets may be sent to your destination, but when you get back, they will not be transferred to you, the routing information in the router on the internet will send the returned packet to the valid ip address, and you cannot receive the packet. However, this behavior may be defined as an ip spoofing, many devices will filter out such packages on the access end, and may not be able to access the s
for the other side of the subnet inside the system to find a router and set up. As we can see from the above analysis, the IP of this interface is not used inside the router because the router gives it an internal number directly.OK, the above router is an entry level, it has 4 subnets below (and the network segment is very average), which is certainly an idealized state, the reality may be more complex. It can be thought that the 4 subnets under this router actually constitute another larger s

1. IntroductionWhen an individual or business entity registers a domain name with a lot of information to register, the settings for registering privacy are various, and we can collect this information and use it to verify the IP space. Based on this clue, you can find information about other websites that belong to that person or business entity, even the number and address of the core employee.The following table is a list of top registries:

defined by the IANAWe know that the Web server usually needs to listen on port 80 in order for all the client browser programs to communicate with it. When a user types a URL in a browser, for example: www.baidu.com, the default port is 80. This port is assigned by the IANA (Internet Assigned Numbers Authority) assignment. In addition, the IANA is administered by ICANN, and its defined ports are as follows:①0-1023: A well-known port that is permanent

Many students will only design the site, but do not know the whole process of building the station. Domain name, space, record and so on. In the internet age, it is necessary to build knowledge and tips in a long and basic network. The so-called enemy, can win. Today, we get some new skills for everyone.
First step: Domain name registration. Cost: About 60 yuan

The remaining 12 are supplemented by root servers, of which 9 are set in the United States and three in the UK, Sweden and Japan.

used to manage the Internet's main directory, the world has only 13 root servers, the name is "A" to "M", of which 10 sets in the United States, the other three set in Britain, Sweden and Japan. All root servers are managed by the United States Government-mandated Internet domain name and number distribution agency, ICANN, for global Internet domain name root servers, domain name systems, and IP addresses.

In this respect, domain name expert Shenyang told reporters that in the international ICANN domain Name System Management, a single number of domain name is limited to protect, is not open to the outside world registration. such as 6.com, 6.net and other domain names do not exist. But China tends to pay more attention to sensitive terms such as politics, and a single
