One successful test of Sohu and sogou Intranet roaming0x01:
During the early tests on sohu network, a large number of sohu IP addresses were collected. For specific cases, refer to my previous cases. This is not the focus.
0x02:
Perform in-depth mining based on the collected ip addresses and obtain the following ip addresses:
220.181.61.204. Actually, it corresponds to the domain name app.m. TV .sohu.com (which was also confirmed later)
At that time,
In recent years, hackers through the Enterprise wireless network initiated by the enterprise Intranet infiltration incident frequency, in a vulnerability platform search found only 2015 years have occurred in dozens of well-known enterprises due to WiFi-related security issues caused by the intrusion of the intranet, the enterprise caused a very bad impact.By the year 2016, wireless network has become an im
The problem is this.

Get Intranet IP address in nodejs, and nodejs get IP Address
Today, my colleague has a demand that the website corresponding to the web server in nodejs can support Intranet access. Later I found that I could modify the hostname attribute in express to my Intranet ip address. However, the problem is that all our machines automatically obtain the
Enable dual NICs to work on both the Intranet and Internet.Problem description: one computer has two NICs, one connected to the Intranet and the other connected to the Internet. The two NICs also need to work at the same time and do not need to be switched out when entering the Intranet, when connecting to the Internet, you do not need to unplug the
Department companies use dual-nic connections, but the Intranet segments are the same. For example:
Intranet Nic IP Address: IP address of the internal server of 192.168.1.0/24 Intranet Gateway: 192.168.1.254 where the ERP server 192.168.1.253
Internet Nic IP Address: 192.168.1.0/24 Internet access network segment Internet gateway: 192.168.1.1

Because the company intranet has more than one server HTTP service to map to the company's external network static IP, if the port map with the route to do, you can only one intranet server 80-port map to the extranet 80 ports, the other server 80 ports can only map to the outside of the network of 80 ports. Non-80-port mapping in the access time to the domain name plus port, more trouble. And the company p
In the company, generally have their own intranet, but also have the connection of the outside network (can connect to the Internet), before the development of the company's intranet, and the next thing and then switch to the outside network, very inconvenient, so I would like to have been the method to make the intranet and the external network together. After s
The proxy server settings have many surprising relationships with the IE region.
The Local Intranet Zone is easy to use. It allows TCP/IP to allow servers on the other side of the earth to access the same server as the server on the lower floor .. on the other hand, the question "local" is left to the user or the network administrator to answer. it is easy to guess that when the machine is a local Intranet
