We all know the usual free ones posted here so I won't go into detail into those. Search for the guides here yourselves but I will list the servers widely known out there:

IPv6
-------
newszilla6.xs4all.nl
weathergirl-ipv6.tele2.net <--------------------Still works but lots of missing articles
reader.ipv6.xsnews.nl <--------------------If you missed the sign-up, like me , you are shit out of luck now. They closed it.


IPv4
-----
free.xsusenet.com ( You can sign up for multiple accounts. Usually a couple times is all that needed. No need to abuse the shit out of it.)
Code:
http://www.xsusenet.com/
Hitnews free.news.newzfinders.com (You can sign up multiple times, every 3 days)



Ok ones that I have found
-------------------------

Xennanews 91.223.220.236 or test.xennanews.com 8 connections (can do 25 but I do 8) port 119 no user name or password needed. **Goes down occasionally but when it works it is great! Tracert goes to XSNews

news.bu.edu 2 connections (maybe more?) port 119 no user name or password needed. **Completion rate not so good. Tracert goes to Boston University duh

jypi.erje.net (IPv6 server) same as above. **Tracert goes to the Amsterdam Exchange and then to Tilaa.net

news.task.gda.pl (IPv6 server) same as above. **Tracert goes to APNIC.net and then to Poland


Semi-free ones
-------------------------

Hitnews with the infinite free trial sign-up (Great one to use)
Code:
https://member.hitnews.com/signup.php

Tweaknews Can sign-up many times for free trial using different IP addresses and various email addresses, without the need for a Credit Card. After about a month, they flush out the IP addresses and you can reuse old ones. 10GB or

10days or whatever comes first.
Code:
https://www.tweaknews.eu/?page=order&product=1
Cheapnews Same as Tweaknews, they even use Tweak servers though, but they are harder to sign-up for multiple times. They require a phone so they can send you a text message. If you have Google Voice, you can use that number once and your cell once. There is a disposable phone number app for Android called "Burner". You get 1 free one and then you gotta pay for more.
Code:
http://www.cheapnews.eu/order.php?productid=7
Xennews Infinite free trial sign-up. Sign-up again in 2 days. Again no credit card needed.
Code:
http://member.xennews.com/signup.php...de_paysys=free
iLoad Never Tried it but I will mention it.
Code:
http://alphaload.iload-usenet.com/tr...D09372FE40CA9E



Here are few more:

free.tweaknews.nl port 119, 4 connections, no user name or password<---------May need a EU IP address for this one to work. I can't get it to work but I have read other people with EU IPs getting it to work (Someone with a EU address want to try and report back?)


dawn.dmz.cs.uu.nl port 119, 2 or maybe more connections, no user name or password <--------has alt.binaries.boneless but missing a lot of articles.

news.synserver.de port 119, 2 or maybe more connections, no user name or password <--------ditto from above

Tip: Use the free trail sign-ups sparingly. If you can't get the file using the regular free ones, then sign-up for a trial.
