What are DNS blacklists ?
This are special namesserver returning spamming servers instead of DNS Records.
The advantages are fast updaterate and the availability. And its works everywhere where DNS is working.

Is my server on a blacklist ? .
You need a DNS query with a special syntax ( with the IP of blog.hlawatsch.org and the dnsblacklist of heise.de [¹] as example) :
the IP: 217.10.14.27
the query
host 27.14.10.217.ix.dnsbl.manitu.net

your server is blacklisted if the returned answer contains localhost.
youre server isn’t blacklisted if the returned answer is empty.

Metalist of free DNS servers

DNS is on of the most important elements of the internet. Without we had to surf with ip adresses. Good to know that you can choose your DNS Server freely and you not depend from the DNS of your provider

There are a lot of good lists with free DNS in the Internet so I link to them instead of building a new one.

custom hosts file for DNS-Problems

Author: Stephan  |  Category: Linux, Netzwerk, Weltgeschehen, windows

After big DNS-Problems at DENIC , manager of the .de domain, I think its not the worst idea to have a hostfile with the most important IPs.

A suggestion

209.85.229.104 google.de
213.144.235.206 ixquick.com

193.99.144.85 heise.de
208.80.152.2 wikipedia.org

213.71.15.101 tagesschau.de

79.125.5.160 robtex.com

This File belongs into the directory /etc at Linux Systems into %windir%\system32\drivers\etc at Windows Systems.
You should use this file only in case of DNS Problems
