I get pings averaging about 8 ms on 1.1.1.1; that's the same as the Vodafone DNS (which the Ultrahub tells me is 203.109.191.1), which suggests they're the same server, or if not, at the same location.  That's not much more than the Ultrahub just across the house at 4 ms.

 

But with IPv6 it's a different story.  Cloudflare's 2606:4700:4700::1111 gives an average of 131 ms, suggesting a trip to the US west coast.  But to Vodafone's 2407:7000:2100:5300::1 it's 8 ms.

 

I wonder why?  Is my ignorance showing?  Any explanation appreciated.

Yeah, that doesn't look right - it should be, and used to be, the same latency on both v4 and v6. I'll get someone to take a look.

you shouldn't be testing dns purely based on latency, that's got a ton of pitfalls if your trying to find the 'fastest' GRC put out a pretty decent tool to get a better idea.

 

 

 

Remember to consider feature sets too when looking at switching, the likes of EDNS0 shouldn't be overlooked.

Poor routing was one reason I left Vodafone. 

 

2degrees fiber, ip4 is a touch faster - it has fewer hops. Bit odd that ip6 goes through metaport and Vocus.

I was just idly checking out the new 1.1.1.2 and 1.1.1.3 services (loosely considering censorship a service), and ran pings to see if they were any different from the 1.1.1.1.  The reports of the new DNS didn't mention the IPv6 versions, so I checked out the obvious counterparts.

 

To use the GRC DNSBench.exe I'll have to install Wine...  I'll make a note if I'm into serious DNS testing.

I'd like to echo this, I'm seeing ipv6 traffic for Cloudflare seeming travelling the scenic route.

IPv4 is very quick to geekzone.co.nz.  

 

Does vodafone not care?  Or is there some Spark-like attitude problem?

@jlittle I am sure the carriers have better things to worry about right now than this!

Looks like we're still waiting on a response from Cloudflare's NOC, I've asked the team to give it a chase.
