Ib lub npe sib txawv hu ua REMOTE_ADDR yog siv los khaws lub qhua tus IP chaw nyob. Txawm li cas los xij, tus neeg siv khoom siv tuaj yeem siv lub npe server, nyob rau hauv rooj plaub twg tus neeg sib txawv yuav muaj nws qhov chaw nyob, thiab tsis yog qhov koj xav tau. Koj tuaj yeem paub tias lub vev xaib surfer yog siv tus IP nrab los ntawm kev saib ib puag ncig cov hloov pauv hu ua HTTP_VIA. Txhua qhov chaw nyob ntawm tus neeg rau zaub mov xaib koom nrog rau cov saw tau muab tso rau hauv nws, sib cais los ntawm commas. Cov servers nruab nrab yuav tsum tso tus qhua qhov chaw nyob hauv tus lej sib txawv npe hu ua HTTP_X_FORWARDED_FOR, tab sis qhov no nyob ntawm lub npe teeb tsa.

Kauj ruam 2
Koj tuaj yeem ua ke los xyuas txhua qhov peb hloov ua ib kab ntawm PHP code, piv txwv, zoo li qhov no:
$ ipAddr = getenv ('HTTP_CLIENT_IP') lossis $ ipAddr = getenv ('HTTP_X_FORWARDED_FOR') lossis $ ipAddr = getenv ('REMOTE_ADDR');

$ ipAddr = txiav nyiaj (preg_replace ('# ^ ([^,] +) (,. *)? #', '$ 1', $ ipAddr));
Kauj ruam 3

muaj nuj nqi getIP () {
$ ipAddr = getenv ('HTTP_CLIENT_IP') lossis $ ipAddr = getenv ('HTTP_X_FORWARDED_FOR') lossis $ ipAddr = getenv ('REMOTE_ADDR');
rov xa mus ua ntej (preg_replace ('# ^ ([^,] +) (,. *)? #', '$ 1', $ ipAddr));
}
