The EnableIPv6 option is incorrectly documented under General but should
be documented under Network instead.

Last time I checked, IPv6 RA weren't supported yet. Is this still the case? Also, why does it default to `false`?

Correct, IPV6 RAs are not yet supported.  And this is  the reason why IPV6 is 
disabled by default.

In iwd versions prior to 1.10 you could let iwd setup IPv4 aspects (using 
DHCPv4) and let the kernel handle RAs.  But, really, such a setup was broken 
because:
   - kernel didn't know anything about route metrics to be used by iwd
   - details obtained from RAs, like DNS, host names, etc were not configured
   - Stateful (DHCPv6) configurations didn't work

Certain setups may have appeared to work, but it was just pure luck.  Given the 
above, and the fact that iwd's IPv6 support is not yet complete, the safest 
option was to disable it by default.

This is interesting to me. I am using connman and iwd (1.10) and have ipv6
enabled on my home network. On my RPi, the ipv6 addresses are listed:
The /etc/iwd/main.conf lists only:
[General]
UseDefaultInterface=true
NameResolvingService=resolvconf

There is nothing referencing ipv6 in connman's main.conf nor in the psk for
the AP I am using.  Yet, I get these addresses when iwd negotiates the
connection:

wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.2.41  netmask 255.255.255.0  broadcast 192.168.2.255
        inet6 fd21:98c8:1d28:0:ba27:xxff:fexx:xxxx  prefixlen 64  scopeid
0x0<global>
        inet6 fd21:98c8:1d28::41  prefixlen 64  scopeid 0x0<global>
        inet6 2600:1700:4320:6caf:ba27:xxff:fexx:xxxx  prefixlen 64
 scopeid 0x0<global>
        inet6 fe80::ba27:xxff:fexx:xxxx  prefixlen 64  scopeid 0x20<link>
        ether b8:27:xx:xx:xx:xx  txqueuelen 1000  (Ethernet)
        RX packets 11056898  bytes 8907204479 (8.2 GiB)
        RX errors 0  dropped 0  overruns 0  frame 0

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

How should I disable it? Should I?

Hi Keith,

If you're using connman, then this discussion isn't really relevant for you. 
You should let connman manage IPv4/IPv6 details.

In fact, this setting is useless without EnableNetworkConfiguration=True.  And 
you should NOT set it if you're using connman.  EnableNetworkConfiguration and 
NameResolvingService are only needed if you're running iwd standalone or do not 
want to use an external network manager, like NM/connman/networkd, for managing 
wifi connections.

That is a question for the connman mailing list.  iwd isn't doing any network 
configuration in your case.

Denis,

Got it! Thanks for the clarification.
