Can 2 dhcp server work together on a lan?

GM2015

Here's what I'm trying to ask:
We're with virgin media, so we don't have ipv6 at home.
The router/modem we have at home can assign ipv6(it seems) to the devices on the wlan, but from what I've seen devices talk on ipv4 regardless.
Of course, I might be wrong, I know less about v6 than a chicken.
my laptop's wlan:

wlan0     Link encap:Ethernet  HWaddr #01-MA-CB-UR-GE-R-PL-S0 
          inet addr:192.168.0.666  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::1af4:6aff:fe03:223b/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:108942 errors:0 dropped:0 overruns:0 frame:0
          TX packets:100117 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:101936526 (97.2 MiB)  TX bytes:13701980 (13.0 MiB)

raspberry pi'2 wlan:

wlan0     Link encap:Ethernet  HWaddr yum-yum  
          inet addr:192.168.0.333  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:73 errors:0 dropped:0 overruns:0 frame:0
          TX packets:81 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:13638 (13.3 KiB)  TX bytes:13662 (13.3 KiB)

It seems the pi can't get ipv6 for some reason by default from the superhub over wifi.
Not even my samsung s3 mini can do ping6 on its terminal emulator, so no idea how to check ipv6 connectivity on wlan. Wifi info doesn't show ipv6, just one ipv4 address anyway.

I managed to "setup" "ipv6" via https://tunnelbroker.net/ by copy pasting their code to debian linux machines and my laptop and rpi had ipv6 connectivity a few weeks ago and the internet seemed even slower on ipv6 sites.

So, I thought about letting the rpi2 be an ipv6 dribbler dhcp server on local wlan, but would the local machines be confused about where to get their IP addresses from?

Could they get their ipv6 addresses from the rpi2 and ipv4 from VM's superhub?

I can't alter any dhcp ip settings on the superhub, so I what I tried to explain might be pointless and not possible.

you don't have any IPv6 (except link-local, in one case) case assigned to this unit, so obviously you get no connection.

It works by pasting their code to /etc/network/interfaces.

auto he-ipv6
iface he-ipv6 inet6 v4tunnel
        address their remote ipv6 address
        netmask 64
        endpoint their closest ipv4 endpoint
        local my local ip on wlan
        ttl 255
        gateway given by them

I got ipv6 on my laptop and the rpi now.

ifconfig output changed on ipv6:
he-ipv6   Link encap:IPv6-in-IPv4  
          inet6 addr: remote ipv6/64 Scope:Global
          inet6 addr: fe80::whatever64 Scope:Link 

I'm getting connect: Invalid arguement when trying to "ping6 myrpi2ipv6 on wlan0 output".

While I can ping6 google.com. I don't really get it.

PI's usually haven't got enable the ipv6 kernel module; check if yours is enable

Regarding the raspberry pi, for some stupid reasons IPv6 isn't enabled by default.
You have to load the ipv6 module: https://www.raspbian.org/RaspbianFAQ#How_do_I_enable_or_use_IPv6.3F
