How do I tell if I have an ipv6 DHCP lease from my ISP?

wkearney99:
I have FIOS, a new pfsense setup and no idea how to tell if my uplink is giving me any ipv6 info.

I know it'll give me a DHCP lease for ipv4 (otherwise I wouldn't be posting this).  How to I determine if there's an active ipv6 lease from upstream?

I have the WAN link using the MAC address from the previous router.  Because, why force myself to suffer the agony of a FIOS support call, right?  This was from an Actiontec router.  Which are supposedly not supported for ipv6.  Now, I don't know if that means it'll get issued an ipv6 lease or not.  I do happen to have one of their more recent routers and could potentially lash it all up again to get a new lease issued to that unit's MAC address.  But I'd prefer to avoid wandering down that road, if possible. 

I have no idea if FIOS is issuing DHCP leases to anything besides their own registered gear.  I mean, they could be and it's a waste of effort to bother with using the old MAC.  But then I open the risk of having to sit for waaaaay too long on the phone with support, trying to beat it into them I'm using a non-standard setup.

Here's what I see in /var/db/dhclient.leases.igb0 (the WAN port on my Qotom Q3554 unit). 


--- Code: ---lease {
  interface "igb0";
  fixed-address xx.xx.xx.xx;
  option subnet-mask 255.255.255.0;
  option routers xx.xx.xx.1;
  option domain-name-servers 71.252.0.12,71.242.0.12;
  option domain-name "verizon.net";
  option dhcp-lease-time 7200;
  option dhcp-message-type 5;
  option dhcp-server-identifier xx.xx.xx.xx;
  renew 3 2018/1/31 18:25:26;
  rebind 3 2018/1/31 19:10:26;
  expire 3 2018/1/31 19:25:26;
}

--- End code ---

ifconfig reports:

--- Code: ---igb0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=6400bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
        ether xx:xx:xx:xx:xx:xx
        hwaddr xx:xx:xx:xx:xx:xx
        inet6 xe80::xaex:fxxf:fexx:xc6x%igb0 prefixlen 64 scopeid 0x1
        inet xx.xx.xx.xx netmask 0xffffff00 broadcast xx.xx.xx.xx
        nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL>
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active

--- End code ---

When I look at the inet6 value I'm noticing there's a number missing in the second position.   xe80:{missing}:xaex:fxxf:fexx:xc6x%igb0

Is that to be expected?


Anyway, rants about FIOS support aside, how do I tell if I've got a live ISP DHCP lease for ipv6? 

I don't 'need this' working now, but if there's something I can/should do to get it running via FIOS I'm willing to make the effort.   Otherwise if I can't then I suppose I'll look into tunneling it, via HE or the like.

In digging through the webUI I can see status_gateways is reporting "Pending" on the WAN_DHCP6 gateway.

FiOS is used by diffrent ISPs, Which Company do you have?

Fontire nor Verizon have any IPv6, so if on those you do not have IPv6.

wkearney99:
Good point regarding which company.  I'm in the DC metro area, so I believe it's FIOS from Verizon directly, not Frontier.

As for not having ipv6, how does one tell?

I don't have to make this work today, but sometimes it's best to configure things when they're new.  I'll put this on the 'to do' list for later.

And perhaps if I'm feeling particularly masochistic.. I'll call Verizon and ask.

Verizon's pages have said IPv6 coming soon (in a variety of ways) for about 7 years, or longer. They have ZERO plans to enable IPv6 on the current FiOS system, there is talk that NG-PON systems will have IPv6, but if you have FiOS (GPON) already you likely won't see NG-PON for a long time.
