New ISP offer static IPv6 address... use it?

My new ISP (Aquiss) offer a static IPv6 address compared to their Natted IPv4 address.

Time to embrace IPv6?

Thanks.

I haven't bothered.

No harm on using it if it's there.

Are they charging for it? If not then go for it. We're still years away from IPV6 becoming the new norm and some ISP who have it enabled it isn't fully such as SKY.

It's free with Aquiss.

Key benefits to IPv6 include:

No more NAT (Network Address Translation)
Auto-configuration.
No more private address collisions.
Better multicast routing.
Simpler header format.
Simplified, more efficient routing.
True quality of service (QoS), also called "flow labeling"
Built-in authentication and privacy support.

Aquiss don't CGNAT do they? Is your reference to NAT in relation to on your internal network?

Nope, you get a static IPv4, free and optional IPv6, and a further 8 (from memory) IPv4 addresses if you wish for a small fee per month.

Just one IPv6 address? I got a block assigned to me. I can't remember how big but I remember thinking at the time "****-me that's a lot of IP addresses!"

ChrisD. · 19 Aug 2022 at 20:53

It's a /56

Yes, that should keep you in IP addresses for a while.

256 prefixes should be enough for any home network

Try harder! In a future where the washing machine, coffee maker and oven all have their own IP addresses it’s probably barely adequate. Before COVID I went to one of those ‘conferences’ where one of the speakers reckoned IPv6 didn’t give you enough IP addresses and when folks laughed he rolled out all the “64Mb is enough for anyone” quotes. He may not be wrong.

So when I configure my router properly for IPV6, instead of a single ipv4 address and me sharing that with my devices on my home network, the IPv6 /56 gives each device its own external IP as such?

Caged · 21 Aug 2022 at 12:24

Yes, every device gets a publicly routable IP address. It's how IPv4 was meant to work, and how it did work for organisations that got onto the internet early. Everybody else had to deal with NAT.

/56 is 256 /64 prefixes, /64 being the minimum subnet size on a segment ignoring p2p links etc. A /64 is 18,446,744,073,709,551,616 addresses

Nobody needs 256 times that at home?

Nobody needs more than 256 VLANs with segregated subnets at home either regardless how many smart devices they can stuff into 1000sqft

To the OP, if they are doing dual stack v4 and 6 then refusing v6 would be pointless, not sure why they’d even ask to be honest, surely they aren’t suggesting v6 only?

The /56 will be provided using prefix delegation then your router is free to use /64s from that bigger /56 prefix on each of its local interfaces and hand out publicly routable addresses to any LAN clients that require it from the /64s

If you’re using the ISP supplied router it probably only has 1 or 2 separate local interfaces anyway (main network and guest usually). If using your own router you could create up to 256 separate VLANs with their own IPv6 prefix each to segregate things but 99.9% of home users obviously aren’t doing this!

WJA96 · 24 Aug 2022 at 05:37

Yes, I admit it, I read @Caged respones as 256 IP addresses rather than prefixes. Thanks you for the correction @Illusion.

ChrisD. · 24 Aug 2022 at 13:02

I'm also with Aquiss, and with Untangle so far, I've not managed to get it working but I'm the first to admit that I know next to nothing about IPv6!

I didn’t think it worked other than to allow the traffic through. I have it working on Mikrotik routers but I’ve not tried it on Untangle because I didn’t think it worked. If I need more than 255 IP addresses I just open the DHCP range from /24 up to something bigger.
