Why will blocking an IP range slow us down?
Time is never wasted when your wasted all the time

It is quite easy to block a complete ip range. I have done it many times.
Normally you would add an ip address to the banned or blocked list by entering the full ip address eg: 183.61.14.74
To block a complete range from, for example an particular isp in china you enter the ip address in your blocked list as follows 183.61.* or 183.61.*.*
This will block all ip addresses starting with 183.61.
While your at it, it might pay to block this range as well, 14.17.*.*

Blocking an ip range should not slow your forum.
Its not just a simple IP range consisting of a few numbers to block, it is made up of a shipload of different ranges which will need to go through htaccess and will check every time you use the forum. I'll try and find a reliable range and test anyway.
Thanks mate but yeah the range I have seen over the last few months consists of a lot of prefixes and seeing the list from other sites has hundreds of lines.
The more rules in there the slower it will be.
Let me check it out more.
Yep but its still easy to block the whole range the way I mentioned and each time a new isp range is detected just add it to the blocked list.
I have successfully blocked out Chinese, Russian, Nigerian and many other troublesome ip ranges
Cheers Ric, the lists I'm seeing that others are using is ridiculously long. At least a few hundred lines of ranges which will effect performance guaranteed.
I've used htaccess on a tenth of there scale and seen performance issues.
Do you still have the china range you used that we could try out?
Russian and Nigerian troublesome............never....... I don't believe you

I'm no IT techo, just an average bloke who runs a few forums.
All we do is block the range as we receive a suspect membership application, eg 183.61.*
It won't stop them all but it will stop anyone using the ip prefix 183.61. which is a good few hundred thousand ips. I don't worry about what other people are doing or any lists. I just set up specific blocks as they try to join.
I do a lot of my checking manually, ie any application I feel is a bit suss I check the ip address to see where its from. I also google suspect email addresses to see if I get any hits.
This website is good for checking ips and email addresses http://www.stopforumspam.com/search

Thanks Ric, yeah we have a good system on here and I have also been literally spending an hour or two each night blocking IP's for the last month or two which is starting to wear me down to be honest...lol
I haven't blocked smaller prefixes though, I should start to try that but the first few prefixes are so scattered I reckon they are using proxy. We did this a while back and I blocked entire ranges which resulted in a lot of genuine countries, including some Aussie members not being able to access the forum.
I'll try out a much larger range and see how we go.
