Title: Verizon fios and DHCPv6-PD?
Post by: sporkman on October 09, 2018, 02:29:48 am
Anyone here on fios and in an area that's had v6 turned up?  Apparently it's "coming soon" to at least the northeast US.

My understanding is that the "PD" there is "prefix delegation".  I'm very confused by that part - if your ISP hands out a new prefix, what happens while all your hosts still have their leases active but the prefix routed to your connection has changed?

Any general issues to be aware of with DHCPv6-PD and opnsense?  Or IPv6 and opnsense in general (I'm coming from another firewall vendor that has 'sense' in the name)?

If the PD changes then that change will be advertised on the LAN and the clients should update, one reason why you should keep the lease time the LAN the same as the ISPs lease time. Note, it's not normal practice for the ISP to keep changing the prefix, some do however. No issues with IPv6 on OPNsense that I am aware of, it's pretty solid AFAIAA.

Thanks - all my v6 experience is datacenter - no desktops, no DHCP. Just a weird idea to wrap my head around that the ISP is possibly cycling my LAN addresses. :)
