Frontier IPv6 Prefix Delegation - AS5650
Hi, Anyone here have a knowledgeable contact at Frontier? I’m on a residential fiber connection and recently started getting a v6 delegation (yay!) but they’re only handing out /64s. Obviously this doesn’t allow for proper subnetting, and forces me to use NPTv6 / ULA if I want to do things “properly”, and devices essentially ignoring their v6 interface. This also seems to be in conflict with RFC 6177 and seems to somewhat defeat the purpose of v6. Any way to get a /56 or more? Support is clueless. Thanks! Chris

Do you have a support address? They seem to have IPv6 route propagation issues too, AS3320 doesn't know their prefixes. -- Gruß Marco Junk-Mail bitte an trashcan@stinkedores.dorfdsl.de
Not via email, at least on a residential line... crappy AI chatbot, or phone support / social media teams that don't know what subnets are. Hoping to come across the right contact here :) On Thu, Aug 6, 2026 at 10:11 AM Marco Moock via NANOG <nanog@lists.nanog.org> wrote:

Good luck… I guess, despite being against best practices, a /64 is better than nothing… especially considering “most” home users really only need a /64. The BNG we are on (backhauled from 200 miles away in a completely different metro area, breaking geolocation, adding significant latency just to get to someone in the same town, etc.) doesn’t even have an IPv6 address period, let alone DHCPv6-PD. I’ve even tried filing an FCC complaint to get the eyes of someone clueful, and that eventually went to Null0. Maybe things will get better now with VZ at the helm. Still better than any other option I can get here.

Similar situation here... mine backhauls about 120 miles, but at least I started getting some IPv6, so, progress, I guess. I just wish they would do -something- with best practice... haha... as you said, still the best option here. Chris On Thu, Aug 6, 2026 at 10:24 AM Tim Burke <tim@mid.net> wrote:

Probably not unless you move to business service. Although it does not hurt (well, your wasted time) to try to convince them to change. For residential, it seems most ISPs believe RFC6177 is more of an idea than a firm suggestion[0], and if you want a /56, you need to upgrade to being what they consider a business site, and, of course, pay more. Comcast does offer a /60 for their residential customers, but if you want a /56 (or more), it is business class service, and Charter (branded as Spectrum) only seems to offer residential customers a /64 (I have not tried, but I presume Charter will offer more for business class). There is almost certainly no underlying technical reason that Frontier could not offer DHCPv6-PD delegations (of some size) to consumer class service should they have decided to do so. [0] There have been previous comments (rants?) on the subject towards ISP's consumer IPv6 service before (including, of course, towards the ISPs that are still not offering any IPv6 connectivity).

it wasn't obvious that Chris had attempted PD though?

Charter gives out a /56 via PD on normal residential service. It's possible that /64 is their default, but sending a /56 prefix hint works just fine. Has for years. On Thu, Aug 6, 2026 at 12:56 PM Gary Buhrmaster via NANOG < nanog@lists.nanog.org> wrote:

Yeah, I am getting a DHCPv6-PD, it's just a single /64, which is better than nothing, but not great. I told support I'd be willing to pay, and it sounds like it's something they don't, and aren't planning to offer. I might even go to their business "home office pro" offering if I knew for sure it would get me a /56 and an SLA and real human on the line when I have an issue. - https://business.frontier.com/home-office-pro - but I haven't tried poking that bear yet, not even sure anyone would be able to answer the question.

You happen to know anything about this? https://business.frontier.com/home-office-pro Would it get me a /56 and real SLA / tech support when needed? Happy to convert if so. Sorry for bombarding you with questions- it’s hard to find people with a clue there 😊 Chris On Thu, Aug 6, 2026 at 1:04 PM Chris Riling <criling@gmail.com> wrote:

Yeah, I am using DHCPv6-PD, they're just delegating a /64, which isn't particularly helpful. All good, not here to spam everyone's inbox on the usual IPv6 ISP rants, was just hoping someone may have a clueful contact. Good to see some names active here that look familiar from when I was working in the service provider space 19-ish years ago - NANOG going strong :) Appreciate the input!

What router are you using? Are you setting a PD hint to ask for a /56? When I had Comcast, the default was a /64, but if you sent a /60 hint that's what you'd get. IIRC it took a little help to change, because their DHCPv6-PD would send you the same prefix, ignoring the hint, if your DUID was in the DB (although maybe a proper release/request worked?). I've always set a hint since, and get a /56 from GFiber. -- Chris Adams <cma@cmadams.net>
It's really no different than regular residential service… I have an “actual” business plan here, and other than options for static IPv4 addresses, it’s the same crud just with a fancier price tag.

My experience with Charter/Spectrum is they used to hand out a /56 with DHCPv6-PD; but after Hurricane Helene we get a /60. Yes /64 is their default."
