但是现在很多无线局域网里多个电脑手机共用一个外网ip，
网上广告商是如何identify用户的？根据外网ip应该不是，那是根据什么
同时又想到当一个无线局域网access point 收到一个网络包时是根据什么机制判断这
个包的目的地是哪个电脑的？ | s*****g

发帖数: 1055 | 4 Good question, according to statistics, average cookie life time is 4 hours,
yes, advertisers still can, this is a very difficult problem to solve, if

If 2 facebook accounts log in with the same ip, it is likely that the other
accounts will show up in friend suggest... Not only facebook, some other SNS
sites do it too.
I think in US it is actually very efficient to track user by IP, at least
for cable Internet(same IP for a very long time). Which law prohibits
tracking by IP? | d*********e
