[EDIT-> - I'm now using Clear's DNS: 203.97.78.43 and 203.97.78.44 thanks to freitasm


I've been a paradise customer for many, many years and the one bad thing about Paradise/Telstra (Other than the helpdesk wait times!) is their DNS Servers.

I've noticed things have been much worse with Paradise over the last 6-8 months.






  • -Often get sites unavailable or very slow to initially display



  • -Youtube clips often sit there without loading



  • -Linux / BSD Package mirrors are often slow / laggy



  • -Problems with websites that run elements on different servers (i.e. embedded chat clients)






The simple fix is to change to someone else's DNS server (I tried to call Telstra last night to let them know my findings but there was a 17min wait time)

I've changed to using Xtra's two DNS servers and the difference on our network is AMAZING, I didn't realise just how bad Paradise's DNS was until I stopped using it.

For example, I use PFSense (a BSD based firewall / router) - It was taking up to 30mins to update Snort (IDS) rules, after changing my DNS they took less than 1 minute!


202.27.184.3   - Xtra DNS 1
202.27.184.5   - Xtra DNS 2

Have a look around the forums, TCL have known issues with their DNS servers. Mauricio has posted about it a lot.

What Paradise DNS are you using? Have you tried TelstraClear's own Clear DNS?

203.97.78.43 and 203.97.78.44

Typo there? - Both are the same.

No I haven't actually, I didn't even realise there were seperate ones for clear.

See the reply time? If you use a third party DNS your reply time can be a lot higher than that and impact your connections...

Thanks, If TCL/Paradise DNS servers are always having problems TCL/Clear although different servers are managed by presumably the same group of people could potentially have similar issues?


freitasm: Reply time...



Yes, that's a lot better, I'll tell you though, even with Xtra's DNS everything was just so much quicker!

freitasm: Have been running Clear's DNS most of the weekend, went OK but not great, switched over to try xtra's and that seemed noticeably faster on most websites, any recommendations?

No recommendations. The only thing to look for is delays on services using CDN such as Facebook and other properties. Make sure the IP returned by Xtra is the same one returned by Clear. Otherwise reply path will get all screwed up.

It's quite odd, Paradise's DNS still has the fastest Query time, but it really seems sites like youtube, facebook and linux mirrors load a lot faster.

I don't think checking the DNS for the root domain will show you what's happening for sub domains and stuff coming from CDN's.

Facebook, Google and Youtube all make extensive use of CDN's (content delivery networks) to handle the scale of their traffic.

Thanks to my good friend Ross who wrote a small script to test all of youtube's servers with a DNS server of your choice:

ClearNet was by FAR the slowest out of Paradise / Xtra's DNS Servers.


using Xtra's DNS:
