for example, if a client has multiple network cards, if you visit a website, will multiple IP come from the same client? Although I think it should be impossible (feel that it is very unreliable to allow multiple IP network cards to access a website, it is not necessary to), HTTP a server should be at most one client, one IP address, right?
I have encountered similar problems. To tell you the truth, this definitely belongs to the divine pit level and needs to be properly dealt with by more business, especially when I was cheated for free.
it is said that there are several specific cases that will occur here. What I can explain is the text. The specific information still requires you to collect and think of ways of
1 multiple network cards. Professional brushes do professional things. In addition to professional brushes, I do not know who will do this. Computers do not have to be too good. Expanding a pile of network cards will not be a problem. You do not need the high-end configuration of the server. Network cards are more than N broadband.
2 if the other party uses numerous usb wifi receivers to add N mobile phone hotspots to the broadband using the local wifi besides the known wifi, I don't know where the limit is. Anyway, a notebook can double open IP an infinite one at the same time, and a cable can be connected at the same time as long as there are a little bit of corresponding computer skills
then comes the reverse of software
all kinds of virtual machines and all kinds of virtual ip can do these things
