Hey guys, i noticed my network devices changes the last 3/4 blocks from time to time especially if devices reboot or reconnect.
Isn't that counterproductive if big point of ipv6 each device have its own ip facing internet without nat while being static, then if it keeps changing from time to time -> you can't connect to your device directly incase if you need to, without checking the ipv6 everytime or using Dyndns.

Am i wrong here?

I host a website under ip6.arpa but right now it isn't really that cool. I want it to be some kind of easter egg type website for anybody who may stumble upon it. Obviously it should also be there to spread awareness of IPv6.

Any idea what kind of website I could make? It has to be working on http only so preferably no user data processing.

Never seen this the highest has been

I just saw this video,

CMIIW work without BGP and only use priority with the route. is it possible?

Funny IPv6 only warning

Hi, My isp provide ipv6 over slaac to customers. I'm on openwrt and has 2 bridges. issue I'm facing is all devices get ipv6 but few devices can route through ipv6 like if my phone gets ipv6 it can utilize it but if my server gets it i can access ipv6 network nor ping any local devices like my phone which has ipv6. server is on different bridge and my PD is /64.

I'm a bit in struggle with ipv6 clients. I want the host names like the Ipv4.

I read a bit in other forums but nothing works.

I got the ipv6 dhcp server adress of my fritz box and maked rdns with dots ip6.arpa. I created a conditional forwarder zone but nothing synced

Maybe someone can explain me something

Swisscom plans to enable IPv6 by default on its mobile network. While this is very late, it is notable because it is the first Swiss mobile network ISP to offer IPv6 connectivity.

A weird anomaly in Switzerland is that fixed-line internet connections already have very high IPv6 adoption, while mobile networks account for the largest share of legacy IP traffic. Migrating mobile networks to IPv6 will propel Switzerland much further up the IPv6 adoption rankings.

We're OpenVPN, of course we like IP addresses!

We launched this calculator - any and all feedback is welcome. Helpful? Not helpful? Basic? WRONG!? Right???

Enter an IP with a CIDR prefix or subnet mask to get the network and broadcast address, usable host range, and wildcard mask.

Per the rules, not trying to sell anything (even if the website hosts our products) - just looking to get validation the calculator is legit from experts.

I've noticed that after looking up, the percentage of my local isp iPv6 internet traffic is below 10%, which is much below the national average here in the US. What is likely the cause of this? Is it the way my isp routes it, or is it because the way their customer router is set up? I'm in a rural area, so it is my only choice.

The proposal uses 192.0.0.11 as a sentinel IPv4 gateway, then resolves the actual layer-2 next hop from IPv6 Neighbor Discovery instead of ARP.

Hi

Here is my problem. I use a GCC6021 as a fiber router. My ISP gives me one IPv4 and a full class in IPv6. I have setup the GCC to pass DHCPv6 request to WAN and so all my devices in LAN have well a routed IPv6 address. For IPv4 I have the usual NAT thing. For IPv4 no problem it all works and I can surf internet using IPv4. For IPv6 although I have a public IP in the class distributed by my ISP no traffic pass through.

In fw it's allowed by default for IPv6 IGMP, DHCPV6, MLD and ICMPv6. Anything else I should use ?

Thanks

Any ideas as to why? I’m with EE FF 900 broadband, using their own router. I’ve noticed that with IPV6, my PS5 Pro’s download speeds are around 10-20mbps, sometimes they just throttle and refuse to download at all. But when I disable IPV6, my download speeds shoot up to around 7-800mbps.

I tried troubleshooting the network on the PS5’s settings, but so far nothing has fixed it except from turning off IPV6 on my router. The issue happened on my old PS5 and also on my PS5 Pro so I doubt it’s a hardware issue.

I’ve also noticed that I cannot connect to my PS5 via remote play when on a different network. But I suspect that this can be solved by opening ports. I’ve yet to try this so I don’t know whether this is also related.

I don’t know much about networks, I may have missed something and my network config is purely stock, I am not using any mesh system/wifi boosters and my PS5 is always wired via Ethernet. I’ve heard that the PS5 does not support IPV6 on its own.

Thanks.

Hello everyone, I'm currently a bit stuck when it comes to configuring NPTv6 in OPNsense. My ISP is not giving me a stable IPv6 prefix which causes all devices to fall back to only their ULA if the uplink fails. As IPv4 takes precedence in this case I've been considering using a GUA for internal purposes and using NPTv6 to map it to the current prefix.

So I set the interface to 'identity association' (for the dynamic prefix), create a virtual IP of the GUA (static prefix) and create an NPTv6 rule that maps the internal prefix (static prefix) to the associated interface. For whatever reason this doesn't work though. Weirdly enough it works when I directly specify the external prefix as the one that's currently assigned to the interface and don't use the associated interface option.

But that pretty much voids the entire advantage it gives me. Is this a bug or am I missing something?

When I had my Calix router installed 2 years ago, my isp didn't enable iPv6. They do offer iPv6 service. I have a Calix GS4220E router. To enable iPv6 under the iPv6 LAN settings on the router web interface does both the RA service and DHCPv6 service need to be set to the server mode, or should I leave the DHCPv6 service in the disabled mode. Also, should the DHCPV6 Mode be set to both stateless or stateful? On the web interface for the router, under internet settings, it says the iPv6 WAN protocol is dhcpv6. Does this mean I should I should enable the DHCPv6 service in the iPv6 LAN settings? I know the RA Service should be enabled.

Yesterday I ask a dumb question, but later after tracking packets on the router, I find out I miss something. The router will response RS with RA, but only if the RS includes Source Link-Layer Address.

I don't know why, but it seems like Debian GNU/Linux doesn't include that field in RS packet. So how can I configure network-manager (or something else) so the Source Link-Layer Address can be included in the RS packet?

Edit: never mind, I found a bug report related to that:https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/work_items/1128

Just in curiosity, why can Android device(not sure if Apple devices can) still use SLAAC and RDNSS to obtain IPv6 addresses and IPv6 DNS server even if the router doens't send Router Advertisement?

Edit: according to some comments and track packages on the router, I find it out that it's because the RS sent by Linux machine doesn't include a MAC address and thus the router doesn't give any response. Android phone includes that and my router gives response correctly.

I want to host a Supertuxkart server but Supertuxkart detects no IPv6, so it only sends my IPv4 address which behind CG-NAT and not my IPv6 address. So because of this my server is only listed with my CG-NAT IPv4 in the server list. I forced Dual Stack in the config, which works because i can connect directly via IPv6 but it still sends only the CG-NAT IPv4 address. Does someone now how to fix this. I know that the STUN servers that are used to test IPv6 are actually IPv4 only but i can't change them because Supertuxkart overwrites them.

It's amazing to me that in 2026 we still have people with such a poor understanding of how IPv6 works. Too many people still believe that NAT is a security/privacy feature. Rob is telling people IPv6 uses GCNAT and you should turn it off.
