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.

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.
