Anything related to the IPv6 network protocol

NetCom 4G and Huawei B593s-22

Sometime ago I switched from a Huawei E220 to a Huawei B593s-22. My 3G internet connection became a 4G internet connection in an instant.

I recently turned on IPv6 on the 4G WAN interface, only to be really disappointed.

NetCom does not offer IPv6 service to its 4G customers. That’s a shame.

With ARIN running out of IPv4 addresses, it sends a clear message that IPv4 is nearing its useful lifespan. NetCom should thus begin offering IPv6 service. Our patience is running out.

ARIN close to Z day

ARIN, the American Registry for Internet Numbers, is closing in on their Z day. Soon only AfriNIC will have IPv4 address blocks available for their customers, and even AfriNIC will run out of IPv4 addresses sometime in the year 2019.

See ARIN’s IPv4 depletion webpage for more information.

The bottom line is: Start using IPv6!

ATEN/ALTUSEN KN2132 and SLAAC

Today at work, we received an ATEN/ALTUSEN KN2132 KVM switch. Unlike our previous KVM switch, this model has IPv6 capability.

Sadly, version 1.8.174 of the firmware contains an annoying bug. If you want to use SLAAC, then the firmware neglects to invert the universal/local bit while transforming the MAC-48 address to a modified EUI-64 format interface identifier. Continue reading ATEN/ALTUSEN KN2132 and SLAAC

Disabling IPv6 autoconfiguration in Windows servers

After long hours of googling at work and at home, I finally arrived at http://www.excaliburtech.net/archives/192, stating this is the way to disable IPv6 autoconfiguration, say when you’re more keen on using a manually configured IPv6 address:

netsh interface ipv6 set interface "Local Area Connection" routerdiscovery=disabled
