Hey guys.

Please note I am not advertising their service, this is just my personal opinion. I'm not involved with any of these companies.


We have Slingshot's AYCE plan.

I'm assuming we have used the standard Slingshot/Callplus DNS configuration, becuase I haven't fooled around with that part of our internet settings up until now.


Here's the question.

I really enjoy streaming channels like the main BBC channels from the UK over our internet connection, and I have been doing so via VPN connection for years even before we got AYCE.

The Provider I used (Zattoo) Got wise, and appear to be blocking VPN connections/Tor connections now from what I have seen.

I did a google search on ways to get round this, and I stumbled on something called Tunlr. It's a free DNS service (I'm not 100% sure how that works, so please feel free to explain to me)

Not only did it give me access to Zattoo at my full ADSL2+ speeds, it also improved my latency and speeds locally.

I used to get on average 10-11mb down. With Tunlr enabled I get 13mb-15mb down. Upload stays mostly the same. I've done tests with Tunlr and Default DNS.

I also took out a paid subscription with Unblock-US, and it also works for Channel 7 On Demand from Aus, which was a suprise, Yet again a similar result with the speedtest.

Why is this?

 

Is it just a coincidence?



Thanks

These services rely on the provider testing if you found their servers's IP via a local (in country) DNS via geo DNS. By using those DNS you are given local IP addresses to the services while people using other DNS services get the out-of-country addresses.

Hence there's no VPN, no encryption, and full line speed (as close as possible to something on the other side of the world).

It may also break access to local caches because of these services not being aware of specific ISPs' configurations.

It's not possible for your selection of DNS server to affect speeds to a local speedtest.

its depends how much lag on the dns servers to convert name to ip address
once its got address then speed should be the same either way
sometimes dns have gone down locally but normally good

however I use acryllic DNS server services for windows (win 7)
it caches the names and ips and does speed up
accessing the same sites over and over again

download it.. its all free.. I use the frontend gui to access
the logs and config and service controls as well
http://dev.arqendra.net/

what you can then do is add the google and other free dns servers
to the first 3-4 in its list then your local one for full back
it automatically adds some for you in default settings
then edit you lan settings for dns to 127.0.0.1 and your done

I find the usa dns update faster then local when you
change the dns servers for a hoster service

The vast majority of routers support DNSmasq (or similar) these days anyway so there aren't any benefits in doing this if tyour router is already caching DNS entries.

i doubt my cheap telecom router does much

but the benefit is more control and can look up and block sites and requests
and also redirect them

theres more benefits then just caching

plus if you dont want to use local dns servers or dns servers that may block sites
for initial lookups

Then problem with changing DNS severs is that 99% of people don't realise what they're infact breaking by using OpenDNS, Google DNS or other 3rd party DNS servers. If you're not aware of the downsides then using them may not be the smartest thing to do.

i mean fall back...

I know some dns servers can insert ads or redirect to ads when dns fails but never been a issue for me and block malware sites for you

but as someone said on a forum


*

Open DNS has services related to their dns servers, such as phishing protection or parental controls, though you may have to sign up to configure them.
*

Selecting a server with better response time can speed up browsing
*

Open DNS now offers an encrypted DNS tool, which keeps anyone from seeing your DNS requests. No matter whose DNS servers you use, your ISP knows every webpage you visit, even if the webpage is SSL, the DNS request is not encrypted even though the connection to the website is SSL encrypted, so they came out with the tool to take care of that vulnerability.

So it can improve browsing speed and security, you may not get both depending on where you are.

You're completely missing the point. Because of how New Zealand is situated in terms of consuming international content there's a lot of reasons to use local caches - some ISPs have local Google caches, there's a Akamai farm in the country and other services give users local distribution.

Using an ISP DNS will point your connection to the right servers - the ones closest to you. Using a US-based DNS will most likely give you servers on the other side of the Pacific. While you may THINK resolution is better, the destination is bad.

Add to this some ISPs have transparent proxies working very closely to their firewalls, you have situations where the response comes back from servers different from the request, and therefore being dropped at the firewall as "unsolicited".

Then people complain about pages not loading correctly, or loading slowly and so on.

But yes, it is your connection, do as you please.

It can't "reduce spying". Who do you think is "spying" on you?

And as for issues, once again it's your connection. If you're happy suffering from a degraded connection that's your entirely your choice.

my speeds fly .. in fact they are faster with caching

if theres ever a issue you just put a exception in the config files.. or stop the service and check

or purge the cache.. the gui makes it simple.

but then I dont use nz sites much anyhow.. depends what you use you connect for.. boring surfing or more for total entertainment

oh theres plenty of spying going on.. just ask dotcom
