JahasFilter

More often than not, when you want to access a website, your computer sends out a request to a DNS server that looks for the IP address you are trying to connect to. Therefore, if you were a network administrator and make sure it is safe from phishing, malware or just want to make sure they do not access the wrong content, then you need to manage things at the DNS level.
JahasFilter is a filter that enables network administrators to block websites based on categories, policies and user permissions. The utility represents the stripped-down version of NxFilter and it should be easier to handle, considering that some of the advanced features have been removed.
In fact, the utility comes with a comprehensive domain classification database that includes over 1.4 million domains that are neatly organized into 53 categories. Consequentially, blocking malicious websites along with those that contain adware, phishing tools or porn on a network level should be fairly easy.
Before you can reap all the benefits it has to offer, first you need to make sure that you select and configure the correct TCP / IP protocol using your dedicated address. While operating it is pretty much straightforward, you need to make sure that you use a DCHP server to set up or modify the current DNS server for all the computers you are managing.System requirementsJava(JRE) 1.7 or higher installed.
