[PHP] IP Ban Script - Rangeban tauglich machen

[djins0r]

Hallo.

Ich habe mir ein Script runtergeladen, dass mir erlaubt andere von meiner Seite zu bannen.
Jedoch geht dies nur, wenn ich die direkte IP eingebe.
Ich wollte fragen, ob jemand das Script so umschreiben kann, dass ich auch die Range der IP eintragen kann. Also dann statt 91.23.03.93 nur 91.23.*.* oder 91.23

Vielen Dank schonmal!

Lies' dir die Literatur zu `regular expressions` durch, das dürfte in deinem Fall wohl das einfachste sein. Auch wenn ein Bann nach Subnetz besser wäre.
