So why are these vro IP addresses looking for computers on campus? From the collected data analysis, it is not difficult to find that these external hosts are mainly looking for three int
We often record audit logs. How can we obtain the real IP address of the client? Let's take a look at the HTTP header. Before discussing how to obtain the Client IP address, we first understand the following three meanings: REMOTE_ADDR, HTTP_CLIENT_IP, HTTP_X_FORWARDED_FOR REMOTE_ADDR is the

Find the start and end IP addresses of a CIDR block
Find the start and end IP addresses of a CIDR blockFor example, for a network segment (192168.1.5/24), its subnet mask is divided:11111111.11111111.11111111.00000000 (255.255.255.0)Note: If the IP

Pay attention to the differences between multicast addresses and broadcasts. From 224.0.0.0 to 239.255.255.255. 224.0.0.1 refers to all hosts and 224.0.0.2 refers to all routers. Such an address is mostly used for some specific programs and multimedia programs. If your host has enabled the IRDP (Internet route Discovery protocol, use the multicast function) function, your host routing table should have such a rou
