Can we recog. Geo Zone from IP? 1

[eman6]

IP addresses are typically four numbers separated by dots.
I am wondering if there is any relationship between geographical zones and this numbering system.
Something like: all IPs in Holland have the second number in 400s (just an imaginary example).
Is there such a thing, or any similar way I can know to which country an IP belongs?

There isn't always a relationship between blocks of IP addresses & actual location. However there are serveral services & database systems that keep track of this. I use the GeoIP tools for my web server stats program. I have also seen site offering paid services of this nature.

Good!
And now, if I somehow realized that 90% of the spam I receive comes from country X (which I actually did), then there must be a way to create a filter to block all of them except those I trust or I know of to be safe or useful.

Yes, Many spam filtering services & systems base part of their evauluation on the country of origin already. The first link in the results below even has some statistics

This is great!!
Actually the only serious drawback is that I cannot give exclusions from the country filter.
However, for my purpose I can let those whom I accept (want to excluse from the filter) use my other emails which don't usually receive so much spam.
Many thanks for this advice. You get another star

Kind regards
Eman
