Internode brings surprise to the IPv6 world

Australian ISP Internode brings surprise to the IPv6 world. It rolls out a native IPv6 trial service over ADSL. Users will be offered a /60 prefix and it is up to the broadband routers of users to allocate IPv6 addresses to their hosts. This is the first time that IPv6 trial service involves prefix delegation to end users. However, as reported by some Australian users, the only compatible CPE is Cisco 877 ADSL router running IOS 12.4 which can handle prefix delegation and IPv6 address allocation to hosts.

The trial service of Internode is more advanced than the current residential IPv6 service of NTT. NTT only offer one single IPv6 address instead of a /60 or /64 prefix.

Number of friends in a facebook account

I recently found that there is a limit on the number of friends in a facebook account. The limit is set at 5000. My question is if someone opens two accounts, how can the status update be propagated to friends of both accounts.

Still on facebook. The word "unfriend" now appears in Oxford dictionary. It has the meaning of pulling out a friend from the facebook friend list. Personally, I think "defriend" might be better. I can quote good examples of starting with de to mean doing something opposite.

The sending domain is "facebookmail.com". This domain is very questionable and is registered with malicious intent. Just wonder why domain name registra can not deny the registration.

rsync to download Fedora Core iso image

More and more mirror sites of Fedora Core offer the rsync capability for getting the iso images. It is therefore necessary for me to practise downloading by rsync. I have tried the following with success :

#rsync -zvP rsync://fedora.mirrors.hkt.cc/fedora/releases/11/Fedora/i386/iso/Fedora-11-i386-DVD.iso .

Note the -P attribute which is quite important to monitor progress of transfer and the estimated time remaining.

HKDNR now supports IPv6 glue records

Last Friday, I was informed by the IT Manager of HKDNR that the .hk TLD nameservers can now support the hosts with IPv6 addresses as glue records. I have tetsted the glue functionality and the results were perfect.

This is a major development in the DNS infrastructure. By allowing IPv6 glue, HKDNR is helping the Internet community in Hong Kong to better prepare for transition to IPv6. By now, I can tell my friends that Hong Kong is not far lagging behind in IPv6 preparedness.
