purchase of paid IP, in fact, is not expensive.Method Two: Paid IPBefore the software, account purchase and so on only provide methods, and did not provide specific software and service providers, this time to provide my usual pay-IP buyers, he is not the most bull I do not know, but basically enough for me to use. Use it according to your own usage scenarios. The specific purchase process will not speak, to play.By the way, another technology to operate IP is to directly use the extraction API
. The IP address has nothing to do with the MAC address, because the Ethernet user can still connect to the Internet through the Modem to obtain a dynamic IP address, which can be inconsistent each time. The IP address usually works on the WAN, And the router processes the IP address. MAC addresses work in local networks. The interconnection between local network
the network number of class B addresses is the number of digits, the host number isClass C Address: 192.168.0.0---192.168.255.255Because the network number of class B address is the number of bits, the host number is 8 bits,Note: These addresses can be reused on different LANs, butIP cannot be duplicated within the

the four segments of the IP address, and the remaining three segments are the numbers of the local computer. If A binary IP address is used to represent an IP address, A Class a ip address consists of A 1-byte network address and A 3-byte host address. The maximum IP address must be 0 ". In Class a ip addresses, the network
The simplest way to connect a server with a socket is to use the IP and port directly, but the Connect method in the socket class does not provide this way, but instead uses the SocketAddress class to pass the server's IP and port to the Connect method. While this is a seemingly troublesome approach, it brings us another benefit: The reuse of network addresses .The reuse of so-called
NAT (Network address translation) is the process of converting an IP address in an IP packet header to another IP address. In practical application, NAT is mainly used to realize the function of private network accessing public network. This way, by using a small number of public IP addresses to represent more private
This article mainly introduces how to generate local IP addresses in python in batches. The example analyzes how to generate local IP addresses and bind them to the network card in Python, which has some reference value, for more information about how to generate
In this article, we are not prepared to discuss technical issues on a large scale. Just to tell you how we will get the IP address of a host. We can do this with the network API in the Win32 API, but in the. NET platform, what should we do? In fact, the operation method and API almost, but we have to understand namespace and class. The site of this aspect of the article a lot, about namespace and class content is not introduced.
. NET platform has a S
We all know that you must be careful when configuring routes on routers and layer-3 switches. There must be no error in IP addresses and subnet masks. Recently, when I conduct a network debugging, I found that improper configuration of the local IP address also causes route exceptions.

My company often needs to debug the
This example describes how Python generates local IP addresses in batches. Share to everyone for your reference. The specific analysis is as follows:
This code is used to generate a local IP address on the local computer to bind to the network card, generate a bat batch fil
In Windows XP, a network card can only be bound with one IP address, which makes it inconvenient for me to access the Internet. This is because when I use a notebook in my unit and dormitory, I need to set an IP address, gateway, and DNS respectively, and reset a network connection. I changed it in the dormitory the night before, the next morning, I had to change it again in the unit. It was so miserable ev
When using Socket to connect to the server, the simplest way is to directly use the IP address and port, but the connect Method in the Socket class does not provide this method, instead, the SocketAddress class is used to pass the Server IP address and port to the connect method. Although this method is obviously troublesome, it will bring us another benefit, that is, the reuse of network addresses.The reuse of ne
In linux, how does one solve the problem that IP addresses do not change in different local networks ?, LinuxipProblem description
When we use linux in different environments, we will find a problem: we call the ifconfig command anywhere, and the address we query is this address. For example, when I was at school, I used the ifconfig command to query the ip address 172.18.250.149. When I call this command
When we discuss how to use Gearman for distributed processing, each machine needs to register an independent job for information feedback. However, for convenience, the Gearman: Worker script register_function code must be universal, so I thought of using their respective IP addresses as job names ~
So how can I get the local ip address as func in the worker script?
The first method is to call shell:
$ip =
Recently, due to the need for a management software for penetrating Internet cafes to restrict vswitches and vrouters. I set 10 IP addresses for the local machine to receive data from hardware.I need to get all the IP addresses of the local machine.Now, you have prepared and used it later.
Bool getlocalall_ipaddress (c
In the past decade, ATM has become an important technology for next-generation networks. It provides unprecedented scalability and cost-effectiveness, as well as support for real-time and multimedia services in the future. In the future information system, ATM will play an important role. However, the current information system, LAN and WAN, is built on network layer protocols such as IP, IPX, and AppleTalk. Therefore, the key to the success of ATM an
Administrator familiar with batch processing commands can also edit a BAT command to complete a series of ping operations. The content of the BAT file is as follows:
FOR/L % I IN (0,1, 255) Do ping X. % I-n 1
Arp-a> IP.txt
This batch of processing files will be listed in the Active IP address and stored in the ip.txt file with their macaddress. Of course, the X. % I in the statement can be modified. For example, if the company network is 192.168.1.0/
broadcast address of type B.
③ The network ID cannot start with "127" in decimal format. The number 127 in the address is reserved for diagnosis. For example, 127.1.1.1 is used for loop testing. At the same time, the first eight-bit Group of the network ID cannot be set to "0", and "0" indicates the local network. I
Network Communication is inseparable from the TCP/IP protocol. In a TCP/IP network, each computer must configure the necessary network to communicate and access resources on the network, some major parameters, such as IP address, subnet mask, default gateway, and DNS server, are required. There are two ways to configur
