Let's talk about it. I also transferred it here, not to lie to PV, so it's easy for me to check it! There are bugs in the so-called "getting real IP addresses" method on the Internet, and the multi-layer transparent proxy is not taken into account.MajorityCodeFor example: String IPaddress = (httpcontext. Current. Request. servervariables ["http_x_forwarded_for"]! = NULL Httpcontext. Current. Request. ser
you receive an ARP answer, the ARP node is complete at this time, so you know the hardware address of the other party. The address is stored in the sockaddr_dl structure,
All data sent to this address will be sent.
3. If another host sends an ARP request or response, and the sender's IP
following two typical scenarios are seen below.1. If you receive a request for a native IP address, send an answer. This is a common situation and it is very obvious that we will continue to receive from that hostData report. It will then be returned to the paper. So. Suppose we don't have a corresponding ARP node for it. You should add an ARP node. Because then weAlready know each other's

If the host in Network a discovers that the destination host for the packet is not on the local network, forwards the packet to its own gateway, which is then forwarded by the gateway to Network B's gateway, and the gateway of Network B is forwarded to a host on network B. The same is true of network B's process of forwarding packets to network A. Therefore, only if the IP
