@dafr0g_ IPv6 connectivity (just like IPv4) must be contiguous all the way from the client device to the server. https://t.co/mqHDLEMNI0

[Scott Hogg @SCOTTHOGG]

Do me a quick favor. Open up Wireshark and set this as the display filter.
ipv6.addr == fe80::/10 || ipv6.dst == ff02::/16
Ooops! I don't think you fully disabled IPv6. 😁
Don't Disable IPv6 https://t.co/MIiojqEhZo

[Scott Hogg @SCOTTHOGG]

@dafr0g_ Yes, but you didn't uncompile it out of the kernel. I bet you can still "ping6 ::1".

@daily_debian As you study IPv6, maybe you'd like to take a free IPv6 Certification exam to test your knowledge https://t.co/MQOWDcy8gK

[Internet Society Pulse @isoc_pulse]

Given that the Internet is a hybrid of IPv4, IPv6, and dual-stack (both IPv4 and IPv6) networks, it is important to understand performance in each IP version https://t.co/wpOyHjakrv

@b_o_f_h_ @sparkfun Here is a video showing how NTP works with IPv6. https://t.co/4CKxyg3Wxl

[Scott Hogg @SCOTTHOGG]

@b_o_f_h_ @sparkfun There are many thousands of them. The NTP pool uses IPv6, and https://t.co/27z2BFrrAc. https://t.co/xKkLqVgTfW

[Hack Glasgow @Hack_Glasgow]

Ready for our next speaker announcement? We're delighted that Vi is coming to Hack Glasgow to present 'Six Years of IPv6'!

After six years of PhD research into IPv6 scanning, Vi will be talking through some of the interesting findings and highlights, including [...]

[Hack Glasgow @Hack_Glasgow]

[...] security issues around IPv6-enabled IoT devices and how to analyse and deal with IPv6 Indicators of Compromise.

For Vi's full abstract and bio: https://t.co/H1bSRAyJPZ

@SCOTTHOGG Thank you for sharing this 🙌🫡🙇‍♂️

This is precisely why I find the topic interesting. People often debate protocol characteristics, while the measurements end up revealing routing characteristics.

The protocol is usually the easy part. The path is where things get interesting.

[Scott Hogg @SCOTTHOGG]

@dbytesmith Thank you too. We have to be careful when interpreting data like this. It isn't that IPv6 is amazing, but its more like IPv4 NAT/CGNAT backhaul increases IPv4 RTT. And IPv6-only devices get NAT64'ed going to many destinations that still only use IPv4.

[APNIC @apnic]

Identifying active IPv6 addresses helps assess deployment, reveal gaps, and detect vulnerable devices. Subnet-Router Anycast (SRA) probing removes the need for prior knowledge of address allocation.

[APNIC @apnic]

Still treating BGP Router IDs like IPv4 addresses?

In #IPv6-only networks, they're simply 32-bit identifiers. @SwerNetworks @DaryllSwer shares structured, human-readable Router ID schemes that scale with modern networks.
