Sperrung wegen IP-Adresse?

Hallo zusammen,
ist die Sperrung auf Basis einer IP-Adresse nicht gefährlich, da diese dynamisch vergeben werden? Ich hatte letztens einen Fall, wo ich einen Nutzer nach Rückfrage manuell zugelassen habe, der wegen seiner IP-Adresse gesperrt wurde. Habt ihr ähnliche Erfahrungen gemacht?

Viele Grüße,
Eckhard

Re: Sperrung wegen IP-Adresse?

Man sollte nicht nur prüfen, ob eine IP in der Datenbank steht, sondern vor allem, wie oft. Und auch, ob beispielsweise die damit verbundene E-Mail-Adresse öfter auffällig war, usw. Es kommt zudem eher selten vor, dass IP-Adressen von Privatanschlüssen gemeldet werden.

Re: Sperrung wegen IP-Adresse?

EN:
In general:

  • Use Email address as your principal means of blocking spammers via SFS

  • An IP represents an ISP (“Internet Service Provider”)
    (the above is a gross simplification, but is often true)

    • Many ISPs provide WAN (“Wide Area Network”) access via dynamic IPs
      (in this case WAN == the Internet, or network of networks)
      (see OpenDNS or Wikipedia)

    • WAN access may be via a sticky dynamic IP
      (meaning that it is the same on every (or most) accesses)

    • If you pay extra your ISP may allocate you a static IP
      (it is the same on every WAN access)

    • Some ISPs have dedicated their service to spammers

Thus, only use IP and/or username as extra confirmation of whether an access is coming from a spammer, and never as the principle ID method. Email address can usually be used as the main or only method to ID a spammer.

As a little bit of technical info, 3 sections of the IPv4 address space are dedicated to be used on LANs (private networks), whereas the rest of that address space is used on WANs  or as multicast addresses:

  • 10.0.0.0/8

  • 172.16.0.0/12

  • 192.168.0.0/16

That should mean (notice the careful use of language there) that you should never see a LAN IP used in the Internet.

There is also the IPv6 address space (“Here be Beasts”).
