Status definition¶

• none: No IPv6 support whatever
• limited: somewhat works, mostly unusable
• partial: mostly works
• most: has most features, can be used productively, advanced features missing
• full: works fully in IPv6 only networks

The list¶

What?	Status
All Mikrotik RouterOS devices	partial (see #Mikrotik-RouterOS)
All Mikrotik SwitchOS devices	limited (see #Mikrotik-SwitchOS)
Arista 7050 / EOS 4.18	most (see #Arista EOS)
Ubiquiti HD AP AC Pro	partial (see #Ubiquiti)

Mikrotik RouterOS¶

As of/until RouterOS 6.44.3, devices can assign themselves IPv6, can route IPv6, but devices cannot be updated in IPv6 only networks (not even with DNS64/NAT64 in place).

What works:

• DNS resolution via IPv6
• CAPSMAN: adding a capsman manually (directly with the IPv6 address) works

Quirks:

• DNS is in the "IP" menu, IPv6 DNS works there, too

What does not work/is missing:

• Upgrade in IPv6 only networks (it tries to connect via IPv4, even if there is DNS64/NAT64 present)
• NAT64: no option in routeros
• DNS64: there is no option for it in the DNS server
• CAPSMAN: cannot discover the capsman via ipv6 address

Mikrotik SwitchOS¶

• Management IP cannot be IPv6
• No IPv6 updates

Highly disrecommended, as they cannot be managed in IPv6 only networks, not even after manual configuration.

Arista EOS¶

As of EOS 4.18.6 EOS mostly works with IPv6. In Arista 7050 with 4.18.6 there is are no NAT64 capabilties.

Ubiquiti¶

The HD AP AC Pro was tested on 2019-05-01 and the result was as follows:

• The mobile phone app only works with IPv4 (discovery, basic config)
• The AP accepts IPv6 from the network via router advertisements
• The AP does not have rdnssd installed, so there are no DNS servers on the AP itself
• It seems the AP stops broadcasting its SSID after some time without IPv4
