Bandwidth is a commodity. High price of international bandwidth traffic surely will cut ISPs’ revenue. Consumers are switching from DSL to fiber-optic and now want to view rich media content like Youtube and live streaming.

To cope with bandwidth demand , TM already placed many Youtube caching server in Malaysia.  No matter how many times you press the play button and choose high definition streaming -  the caching server will supply you the cache.  During AAG cable downtime recently, popular Youtube videos streaming fast like always. This is because of local caching servers are placed locally in  Malaysia.

Propagation What? http://blog.datakl.com/2011/07/prop-propagation-what/ http://blog.datakl.com/2011/07/prop-propagation-what/#comments Wed, 13 Jul 2011 20:41:01 +0000 admin http://blog.datakl.com/?p=505

What is domain name propagation? For new domain name propagation is a period where you newly registered domain being sent to all name servers (or DNS servers) in the world.

Hosting Migration

Hosting Migration

DNS server caches of your domain name mapping to IP address. This mapping record normally stored for time period to prevent querying or lookups. For example www.datakl.com resolves to 210.48.148.207 and stores in DNS servers around the world for 6 hours.

DNS servers drop stale DNS record based on few factors such as DNS record timing setting and
the practice of flushing records every interval period (normally ISPs)

Your computer stores DNS record for faster browsing to eliminate frequent DNS query to DNS servers.
The caching is beneficial for faster browsing but if you are in the midst of change hosting company or server, this process could cause confusion or downtime. Why confusion? In hosting or computing everything is almost instantaneous – upload your html/php coded page you can view instantly but for DNS the only solution is to wait!

On and off explains (After changing name servers I could view my web site for a moment and later turns to page could not be found or referring me back to old hosting server why?)

Normally your computer or router/modem use two DNS servers or more. The first (on) probably responded by a DNS server which has your newly modified record and the (off) page could not be found now could cause by another DNS server that still keeping your old DNS record -(error page could not be found or returning you to your old hosting company)

Just wait for propagation period to compete – normally 48 hours and your web site will resolve properly. Try on your luck by rebooting your computer – normally rebooting will flush the old DNS record in your computer or use ipconfig/flush command if you are using Windows DOS prompt. To have less impact on your operation or visitors, change your DNS during non busy hours is recommended – after office hours.

SKMM or Malaysian Communications and Multimedia Commission (MCMC) has released an official order to block access to file sharing web sites to all ISPs in Malaysia. The order given based copyright grounds.
P1 Wimax provider uploaded the official letter to its wall on social media site – Facebook.  The move is quite drastic and will surely enrage internet users in Malaysia.

Access Denied

Access Denied

The blocking will be done via DNS resolution query ;  null route the query to deny access.  To  bypass the restriction simply  using  this method.
Many users use file sharing to send huge files to be distributed to friends or clients abroad. Since email transmission is impractical (25MB attachment max) and Anonymous FTP is no longer provided by web hosting provider due to security and abuse, users may have to use other file sharing services not listed in the list.

On April 15 – Apnic – The Asia-Pacific Network Information Centre (APNIC), which is the organization responsible for distributing IP address (IP) in most of Asia, Australia, and the Pacific announced that they no longer have IP address to be distributed.  Chinanet Fujian Province Network apparently the last company to snatch half a million of IP addresses allocated for Internet Service Providers (ISP).

The only solution is to accelerate the implementation of IPV6 but many ISPs especially in Asia pacific region is still not IPV6 ready.  IPv4 uses 32-bit addresses and can support 4.3 billion devices connected directly to the Internet. IPv6, on the other hand, uses 128-bit addresses and supports a virtually unlimited number of devices.

APNIC is holding 16.7 million IPv4 addresses, but the body still has reserves for other usage.  According to Apnic the exhaustion due to IPv4 the growth in fixed and mobile networks experienced in the region.
