Mikrotik with only IPv6 connection trouble.

RouterOS General
1

Hi!
Tell me how can I configure mikrotik to work with gray ipv4 without access to the Internet and ipv6 obtained by RA (with dns advertising):

[admin@mikrotik] > ping 2001:4860:4860::8888
SEQ HOST SIZE TTL TIME STATUS
0 2001:4860:4860::8888 56 45 40ms echo reply
sent=1 received=1 packet-loss=0% min-rtt=40ms avg-rtt=40ms max-rtt=40ms

[admin@mikrotik] > ping dns.google.com
SEQ HOST SIZE TTL TIME STATUS
0 no route to host
1 no route to host
sent=2 received=0 packet-loss=100%

[admin@mikrotik] > ping ipv6.google.com
invalid value for argument address:
invalid value of mac-address, mac address required
invalid value for argument ipv6-address
failure: dns name exists, but no appropriate record

[admin@mikrotik] > ip dns print
servers:
dynamic-servers: 2001:4860:4860::8888
allow-remote-requests: yes
max-udp-packet-size: 4096
query-server-timeout: 2s
query-total-timeout: 10s
max-concurrent-queries: 100
max-concurrent-tcp-sessions: 20
cache-size: 2048KiB
cache-max-ttl: 1w
cache-used: 12KiB

[admin@mikrotik] > ip dns cache all print
Flags: S - static, N - negative

NAME TYPE DATA TTL

0 ipv6.google.com CNAME ipv6.l.google.com 5h59m20s
1 l.google.com SOA ns1.google.com 20s

And even if I add a static entry in dns ping does not work:

[admin@mikrotik] > /ip dns static add address=2001:4860:4860::8888 name=www.qqq
[admin@mikrotik] > ping www.qqq
invalid value for argument address:
invalid value of mac-address, mac address required
invalid value for argument ipv6-address
failure: dns name exists, but no appropriate record

There’s a problem with this for many years (see this thread). It looks like “ping ” looks only for A records. A workaround for IPv6-only hostnames is “ping [:resolve ]”. But according to my quick test, even that fails when hostname has both A and AAAA records, because :resolve still prefers IPv4 address if available.

It’s so bad… - i have network which use mikrotik (about 250+ pcs) switch and router’s and want update firmware in it’s via ipv6… and ipv6 i need not only for ping’s :slight_smile: but for upgrade firmware and control this devices… I think Mikrotik as hardware developer want to be IPv6 ready and compatible not only as home user device developer but as ISP hardware developer too but this now under big question…

Second question - someone know - mikrotik have ability update firmware via ipv6?

If you don’t insist that the router itself must download it from internet, you can upload new RouterOS packages yourself.

I do not insist! but you will not argue that today such a poor and partial implementation of ipv6 is embarrassing for the manufacturer?

I’m big fan of RouterOS, but not big enough to defend that. :slight_smile: But that’s how it is, hopefully the new RouterOS v7 will get things moving…

+100500!
ROSv7 will be,may be…but what we must do today? :frowning:

Wait or look elsewhere. At least there’s already beta of v7, so there’s increased chance that we’ll live to see the final version, with all the wonderful and needed improvements.
