Mikrotik IPv6 addresses

NAB · Mon Feb 21, 2011 11:34 am

I see that Mikrotik have allocated IPv6 addresses to their web server (www.mikrotik.com --> 2a02:610:7501:1000::2), forum (forum.mikrotik.com --> 2a02:610:7501:1000::201) and primary MX (mailgw.mikrotik.com --> 2a02:610:7501:1000::199).

Unfortunately, none of the addresses in question are responding to the appropriate services. Yes, of course, browsers will fail back to IPv4, but only after a significant wait.

Basically, this means that, to all intents and purposes, Mikrotik doesn't exist when the end user has an IPv6 connection.

Nice. Not.

Looks like it works for some, and doesn't work for some others. Can anyone else try this?

Can you try http://test-ipv6.com
and http://www.whatismyipv6.net/?s=IPv6_traceroute

NAB · Mon Feb 21, 2011 11:51 am

10/10 on test-ipv6.com and no problem tracerouting to our gateway - 2001:8b0:fff1::

Beccara · Mon Feb 21, 2011 11:53 am

Can you provide a trace route to the MT ip?

so far (also from http://forum.mikrotik.com/viewtopic.php?f=2&t=49164 ) it looks like HE is having problems

Beccara · Mon Feb 21, 2011 2:09 pm

Seems like it would be worth talking to your Upstream Normis, You have 2 networks HE.net and retn.net both unable to get near your netblock. Normally 1 network I blame the network, 2 networks and I blame the network I'm trying to get to

Retn.net is not touching HE.net

you are right, we are working with them right now. looks like this ipv6 migration will not be so easy

Fun problem

Still looks like an issue with MT v6 transit provider, It could be that it's not getting a full route table or not getting the route for this guys connection

They told us that IPv6 is still in testing stage, and we shouldn't be surprised that stuff breaks

Beccara · Mon Feb 21, 2011 2:47 pm

I've heard that before, We told them their SLA states IP connectivity and didn't state which version. IPv6 became stable very quickly after that

janisk · Mon Feb 21, 2011 2:59 pm

you can go to http://www.sixxs.net/tools/traceroute/

and check with different sources availability of certain ipv6 addresses, for example, mikrotik.com address from different providers/places on Earth

edit: just check if you set IPv6 traceroute instead of IPv4

NAB · Mon Feb 21, 2011 2:59 pm

That's fine, but then you shouldn't have created AAAA records for your existing FQDNs - perhaps 6.www.mikrotik.com and 6.forum.mikrotik.com (or whatever) should have been used until testing's complete?

However...

Indeed, it seems that there is no a quad-A resource record for www.mikrotik.com.

Out of curiosity I tried accessing Mikrotik web over IPv6:

cya in a few days @budapest mum

unfortunately AAAA entry was removed for www.mikrotik.com as we encountered unforeseen problems that cannot be resolved by us.

both addresses of download.mikrotik.com should be reachable by now. (at least i was able to at the time of writing)
