How to Block a Range of IP Addresses
As much as content creators want traffic to their website, there is such thing as the wrong type of traffic. Sometimes it's content scrapers, sometimes it's malicious bots; either way, it's important to know how to block problematic IPs from your site.
To block a range of IP addresses using an .htaccess file, you can use the * wildcard for pieces of the IP address:
Order Allow,Deny
Deny from 219.198.*.*
Allow from all
You can also use a regular expression:
RewriteEngine on
RewriteCond %{REMOTE_ADDR} ^219\.198\.\.
RewriteRule ^ - [F]
Don't let known attackers and problematic bots bring your website to a halt! Be quick to check your site logs and ban addresses that are causing havoc!

![JavaScript Speech Recognition]()
Speech recognition software is becoming more and more important; it started (for me) with Siri on iOS, then Amazon's Echo, then my new Apple TV, and so on. Speech recognition is so useful for not just us tech superstars but for people who either want to work "hands...
![jQuery Link Nudge Plugin]()
A while back I debuted a tasteful mouseover/mouseout technique called link nudging. It started with a MooTools version and shortly thereafter a jQuery version. Just recently Drew Douglass premiered a jQuery plugin that aimed at producing the same type of effect.
Who is using Apache today? Just kidding. Do you know how to achieve the same using Nginx? Thanks in advance.
