Hello, I've just tested to both IPv4 and IPv6 addresses from one of my RB2011 (Slovakia, Central Europe) on ROS 6.45.11 and both worked great, Thank you!
On IPv4 I've got approximately 75/65Mbps and IPv6 was even 95/85Mbps (UDP both way).
Those speeds are good enough for the installation site, but I wonder what would cause such a difference?
Could it be just my provider prioritizing IPv6? Configuration issue on my side? Is it to be expected?
In my opinion …
There are two methods to implement IPv6 routers/networks (with the current IPv4 networks).
- use/build Dual-Stack routers/networks ( were routers in a network are both IPv4 and IPv6 at the same time )
- Add IPv6 routers/networks next to existing IPv4 routers/networks (where you have a mix of only IPv4 routers/networks -and- only IPv6 routers/networks)
Both methods to implement IPv6 work well. ( I'm building both types in my IPS/WISP networks - where some networks use only IPv4 sitting next to only IPv6 routers/network … and other parts of my network are Dual-Stack ( both IPv4 and IPv6 ). There are advantages of both methods to implement IPv6 into your network.
If an IPv4 router is pretty busy/saturated then you have two options , upgrade hardware to support both IPv4 and IPv6 - - - or - - - add additional IPv6 only hardware next to your existing IPv4 hardware. There are pros and cons of both methods.
Edit: Also , IPv6 traffic through the Internet may use different paths (hops) through the Internet verses IPv4 paths (hops). Thus IPv6 traffic has a high possibility of going through totally physically different routers/switches/networks that IPv4 traffic goes through.
In answer to your question - I suspect it simply comes down to what method each Internet hop and built and how busy each device is.
