IPv6 discussions

[Mach3.2]

Oh that's certainly new, but makes sense considering the level of load that 5G users would put on the CGNAT gateways. Is it only enabled on 5G? Or does it still work if you force it down to 4/3 etc?
When are the apn settings? do they differ from older plans?

same APN name, user name and password as far as i can tell.

After toggling between 4G, 5G NSA and 5G SA, I think IPv6 is only available on the 5G SA network, which could explain why sometimes I get no IPv6 address/connectivity.

The problem you're seeing is because in dual stack mode the iphone won't keep retrying to connect once it has any (legacy *or* v6 connection), so if you go to a location with marginal signal you might find that the legacy negotiation succeeded and the v6 did not. It's likely that you're using dual stack, or dual stack is still offered as a fallback. V6-only negotiation can also happen, but only if the network has NAT64/DNS64.

Yeah I get that, I was checking the cellular interface and it doesn't receive IPv6 addresses on occasions, probably due to the reasons I mentioned above.

First off thanks for the long detailed reply. Many points are what i've already read aand known about and agree with. My exp trying out singtel on ipv6 probabyl left much to be desired (slower overall speed, latancy and responsiveness) but hearing the postiive feedback gonna give it another go when my home switches over to SH. Overall honestly i expected it to have been picked up much faster tbh, but i guess i underestimated how willing msot of our ISPs are in the move to IPv6 many years back.

Yeah singtel until recently only had a tunnel, which is always going to give a poor service as such tunnels were only really intended for very early experimentation.
For point of comparison, starhub also offered an ipv6 tunnel on their old cable network (their fibre network has always had native v6), British Telecom also offered a tunnel service back in 2000.

Newer equipment, and 5G SA requires v6 for voice. While it's possible they could limit it to voice-only, that would be a pretty stupid thing to do and would only increase costs for them.

It would appear then based on the apnic stats, that roughly 3% of users are on 5G SA.

In France the telecoms regulator mandated v6 as a requirement for a 5G license.

For our next SingTel SIM Only Plus recontract, we should be able to get 5G without paying more. And from the reports, Singtel 5G SA coverage has improved by quite a bit.

Yeah hopefully they give it to everyone as standard soon. It's a little like the early days of 4G, where they charge you a hamburger every month just to have it.

Just like our gov now push into 10Gbps i sincerely hope they have ipv6 as a requirement not just pure speed.

Our IMDA had last year PR piece touting digital blueprint for next 5/10years....

Not even a single mention on IPv6 in their Digital Connectivity Blueprint Report

what is IPv6?

too technical for people to know what's IPv6

The other thing to consider is that IPv4 is now actively harmful and is stifling development, and anyone not using IPv6 is contributing towards this.

Go back 20 years and if you set up an ISP you could get enough IPv4 for your customers + growth room, then simply route the addresses to customers. Set up an ISP today and you'l get put on a waiting list (possibly waiting a year or more) for a maximum of 256 addresses. This is not enough for any serious number of customers so you're faced with:

• Buying more addresses at auction, high cost and you're bidding against giants like Microsoft and Amazon.
• Use address sharing mechanisms like CGNAT, but then you:
  • Need NAT equipment in addition to the routers (cost+++), NAT in either hardware or software is necessarily much more complex than routing (ie you need to lookup every packet against a state table, store the table in quickly accessible memory etc) so for the same level of throughput you have higher complexity, higher cost and higher energy consumption.
  • Provide an inferior service, which leads to customers being unable to do things which are taken for granted on existing services in developed countries, causing your service to be viewed as second class.
  • CGNAT also increases costs in other ways, for instance forcing traffic to transit (expensive) international links instead of doing local p2p.
• Most do a combination of both, reserving dedicated addresses for higher paying business customers.

This makes it MUCH more costly to set up an ISP, while still providing an inferior service than incumbent suppliers.

• In a developing country this means your costs are higher, while your potential revenue is lower because the potential customers have less disposable income. Generally corners are cut in order to meet a price point the local market will take, so you end up with equipment intended for gigabit fibre being used to provide services that are capped to 10mbps so as not to overload the limited NAT capacity etc.
• In a developed country your service finds it harder to compete because it's seen as inferior and your margins are thinner than incumbents. The incumbents can always force you out of the market by lowering their prices below your cost threshold.

The more things move to IPv6, the less of a harmful impact this has until eventually it goes away entirely - resulting in faster development in developing countries, and increased competition in developed countries.

One potential issue with IPv6, maybe this is specific to Singtel that IPv6 routing may be worst than IPv4. One example is to M1 OOkla SpeedTest server which @Mach3.2 already analyzed.

I was revisting the latency to various public DNS servers with filtering and then I can see that IPv6 latency is much worst than IPv4 in some cases. The reason is probably the same as above.

1) One example for Singtel is with family.freedns.controld.com and p4.freedns.controld.com.

@Mach3.2
Please help to test on M1 side to see if you have such issues or not. Thanks.

@firesong
If you got the time, please help to test on Starhub side to see if you have such issues or not. Thanks.

Note: Windows will default to IPv6 when it is available.

2) For Singtel, IPv6 is also much worse with Cloudflare family DNS.
M1 has no such issues based on the test from Mach3.2.

Not saying M1 doesn't experience different routing for IPv4/IPv6 traffic because I most certainly do on occasions.

I'm not aware of anyone other than you who's got the native service.

One more report in the Singtel 1Gbps thread.

Same problem though -- high latency to Cloudflare using Singtel IPv6 compare to IPv4.

https://forums.hardwarezone.com.sg/threads/singtel-1-gbps-fibre.5930834/page-237#post-152910976

It works for me but...

Unsure if really worth it for now as mentioned in another thread. test done via wired ethernet

Not bad. Seems like there's improvement from singtel to cloudflare ? Last time must go via HK?

Yes, Singtel IPv4 to Cloudflare is now quite good, last time it was like 30ms to 40ms, now down to about 3ms.

Not all probes getting better latency to Cloudflare, but was better as compared to half a month ago.


AS3758: https://atlas.ripe.net/measurements/74591934/results
AS9506: https://atlas.ripe.net/measurements/74591979/results

Half a mth ago:
https://atlas.ripe.net/measurements/71332243/results

Aslo interesting that there are probes on AS3758. Doesn't singtel fibre customers get allocated an IP under AS9506?

Edit: AS3758 is likely to be biz internet.

my ping to cloud flare still 30-40ms. With no real solid evidence (just my own ep, It feels like Singtel has different routing for each of their different public IPs for whatever reason. Own (admitedly not scientific or controlled) exp was that I used to have lower ms pings to cloud flare, but ever since I got a new IP its mbeen 30-40ms and routing to certian Local game server (namely Apex Legends SG server) has been severely affected. (talking about 200ms ping or ping spikes randomly up to 200ms)
