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.

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”).
