dns black listed?

post #1 of 5
Thread Starter 
ok!i use various tool like namebench or dns benchmark (grc.com for the later)my issue:
http://ip-blacklist.e-dns.org/
using this tool i found out a lot of dns were blacklisted!a lot of them in fact only google seemed to steer clear of this!
could any explain what the ods are that only one corporation steer clear of being black listed when comcast or other bigger name get black listed!
is google blacklisting all dns not being themselves via unknown means?
and what is the effect of a dns being blacklisted?
do any know if microsoft supply a free dns like google 8.8.8.8 or 8.8.4.4
cause i would like to see if ms is also blacklisted!
ty if any advanced tech in this field could shed some light!

What is an IP DNS Blacklist?
IP blacklists are maintained lists of known or suspected spammers. This IP blacklist tool checks to see if your IP address is included on a public IP blacklist. Occasionally, legitimate websites or mail servers can be erroneously included into IP blacklists. This can cause your emails to be rejected when they are processed by the receiving SMTP server.

This is for SMTP, Black lists are a way of blocking spam and lists liek SPAMHAUSE use this technique, the black listing will have no effect for the average home user unless you want to start a email server

To my Knolage Microsoft does not opperate a public DNS server,

And the reason google probley wont have been black listed is people are scared of blacklising them (that was a joke ... DNS servers should not be outputting SMTP so they shouldnt be a need to blacklist them, unless its to catch IP spoofers)

I had this happen to one of my boxes that I was too lazy to close back up the open proxy after I was done with it and some individuals/bots pounded on it until the bandwidth limit was reached.

Seems to do a reverse DNS check to spamming IPs and marks both your matching rDNS entry as well as your IP into some blacklist database for a certain time period.
