Blocking Google Analytics and Statcounter

Domains 4 Comments

Web analytics software available today are designed with one quote in mind “Information is power”, so they collect a ton of information about you, the Internet user. This includes your location (Country and City), web browser used, referred page, your IP address (Google Analytics doesn’t show this info to webmasters), time on site and a wealth of other information. While there are lots of web analytics software available the two most popular of them are Google Analytics and Statcounter.

Types of DNS Records

DNS (Domain Name System) is an internet system which translates domain names into IP addresses. This is the definition that you commonly see around the internet, but practically it does much more like resolving mail servers for a domain, mapping an alias name of a domain to another domain, inform mail servers which sources of emails they should trust when they receive email from a particular domain and the list goes on.
