About Sixscape

Sixscape Communications was founded by Lawrence E. Hughes in 2013, and a year of research and development was done to create the initial products.

Sixscape Communications Pte. Ltd. is officially registered as a for-profit limited liability corporation in Singapore. The registered address is 33 Ubi Ave 3. #05-54, Vertex (Tower A), Singapore 408868.

Why Asia?

Why does Sixscape need to be in Asia? Many countries in Asia have been investing heavily in IPv6 (the replacement for IPv4) for many years. The Internet Protocol (IP) is the foundation for all Local Area Networks and the Internet itself. The current version (IPv4) is 30 years old, and now is at End of Life. There is no viable alternative to IPv6. Think of it as going from horses to cars - only no more horses are being born. Staggering amounts of money will be spent upgrading network equipment and software, and training engineers, over the next 10 years.

Deployment of IPv6 is well underway in Asia, especially in Japan, Singapore, Malaysia, China and now Hong Kong. APNIC (the source of all IP addresses for Asia/Pac) reached the end of normal allocation of public IPv4 addresses back on 19 April 2011 (the first Regional Internet Registry to run out), so IPv6 is no longer "the future" here in Asia. Rather, IPv6 is "the present" and IPv4 is "legacy". IPv6 is essential for bringing the Internet to tens of billions of new users and devices in Asia/Pac. Just as countries here were getting serious about connecting to the Internet, IPv4 ran out.

The EU and Middle East will be the next region to "get serious" about IPv6, starting about a year or two after RIPE NCC (the source of all IP addresses for EU and the Middle East) reached end of normal allocation of IPv4 (14 September, 2012). Latin America reached end of normal allocation (their final /10) on 10 June 2014. North America will not get serious until 2016 or 2017, a year or two after ARIN (the source of all IP addresses for North America) reaches end of normal IPv4 allocation (probably February 2015).

This means that the APNIC region will always be several years ahead of the rest of the world in IPv6, even though IPv6 will be used globally for decades to come. Since the main thrust of Sixscape is IPv6, we had to be located in Asia. Out of all the possible locations in Asia, Hong Kong and Singapore were the top choices. For a variety of reasons, Singapore turned out to be the better choice.


Why Singapore?

Why does Sixscape need to be in SIingapore? Singapore is one of the great cities of the world. Like Hong Kong, it is a modern and affluent city/state. In 2010, Singapore had a population of 5.17 million compared to Hong Kong's 7 million. 

The Singapore government is investing heavily in Singapore as an IT hub, It also has many excellent universities, which will be a great source of talent as Sixscape grows. It has a thriving entrepreneurial community. It also has a growing venture capital community. The Singapore government is investing in IPv6, and the percentage of networks that support it here is rapidly growing. There are as many IPv6 Forum certified engineers in Singapore (440 as of 2013) as in the rest of Asia/Pacific combined, and more than in the U.S., which has 60 times the population. Our CEO (Victor Tang) is responsible for training most of those.

These are the necessary and sufficient conditions for an entrepreneurial success.


Why Me?

Why am I the one creating Sixscape? I am a serial entrepreneur with 40 years full time experience in the IT field. My first venture ran from 1982 to 1987. The second one was in 1988. Those were both learning experiences. From 1993-1995 I lived and worked in Hong Kong. During 1998-2000 I worked for VeriSign (then the leading company in the world in cryptography and PKI), where I created the training and presented it internationally to affiliates and large customers (and in the process learned PKI from the top experts in the world).

My third venture (CipherTrust) was based in Atlanta. It started with 6 people in my basement in 2000, and US$3M in funding from my partner Jay Chaudhry and me. That company did a US$42M VC round in 2004, grew to 250 people, and sold for US$273M in 2006. I was co-founder and the first CTO.

I launched my fourth venture, InfoWeapons, based in the Philippines, in 2004. We built several service provider class appliances and were one of the official IPv6 Ready testing centers. I also created IPv6 Forum certified training (and certified over 100 telco and ISP engineers around SE Asia). I presented papers at many IPv6 summits and conferences all over Asia, Europe and the U.S. during those years. For most of that time, I was impatiently waiting for IPv6 to finally take off. As of about mid 2012, it finally did (at least in Asia).

Therefore it is time to launch a much more serious effort. The name is inspired by one of the most successful Internet startups ever, but based in the IPv6 Internet - kind of NS-TNG with a whole new cast. Make it so, Number One! Some of the products are from InfoWeapons (SolidGate and SolidProxy). There are also some new breakthrough products underway, initially in Network Management, later in Peer-to-Peer secure communication and file transfer. All of the products are designed to help people learn, deploy or manage IPv6, or they will take advantage of some of the amazing new capabilities of IPv6.


The Website

This website is hosted at Hurricane Electric's Co-location facility, where we have native 100 MBit/sec dual stack service (highly recommended!). The website content is managed with Joomla 2.5 and runs on Apache 2.2 / PHP / MySQL, in a FreeBSD jail.

This website contains possibly the most comprehensive collection of free information on IPv6 anywhere, including the full content of the IPv6 Forum Network Engineer Silver training class. This training has received the IPv6 Forum Certified Course credentials (see course outline). It also contains do-it-yourself projects that you can use to learn IPv6 and begin your own deployment, at very low cost.

The main domain name (www.sixscape.com) has both AAAA and A records published in DNS, so it is available over both IPv4 and IPv6. If you have IPv6 service, most browsers will prefer connecting over IPv6. If you don't have IPv6 service, your browser should immediately connect to the IPv4 address.

There are two alternative domain names. The first, www4.sixscape.com has only the A record published (this allows you to access the website over IPv4 even if you have IPv6). The second, www6.sixscape.com has only the AAAA record published (this will only connect over IPv6 - if you have only IPv4 service you will not be able to connect to this URL.) Some browsers are now implementing "Happy Eyeballs", so even if you have IPv6, and the website is available over IPv6, if an A record is available, your browser may choose to connect over IPv4 (it depends on which connects first, IPv4 or IPv6). If you want the real IPv6 experience, use www6.sixscape.com! Currently, you get the same content whether you connect over IPv4 or IPv6, but later I may provide premium content, available only over IPv6 (perhaps functionality that simply doesn't work over IPv4).

For Firefox, I recommend the sixornot addon, that shows you the IP address you connected to, plus all of the IP addresses that were returned by DNS. I have not been able to locate an equivalent addon for Explorer. It would be nice if browsers had something like this built in (kind of like seeing the lock icon when you connect over SSL/TLS), or some mechanism that would allow you to force use of IPv4 or IPv6 (similar to using https: instead of http:). Some people use the nodename ipv6 instead of www (like ipv6.google.com) to force connection over IPv6. I prefer the www4/www6 approach - this will work with any protocol (e.g. sshd4/sshd6, ftp4/ftp6, etc). It's really easy to publish alternative domain names in DNS. With command line tools, many have a -4 or -6 option (e.g. Windows "ping" command).


Another Useful IPv6 Website

You may also find www.v6address.com of use. You can leave off the "www" if you like. The main page shows you the IP address from which you connected. The www4.v6address.com URL publishes only an A record, the www6.v6address.com URL publishes only a AAAA record, while www.v6address.com publishes both A and AAAA records. If you have a browser that won't let you disable "Happy Eyeballs", you can force use of IPv6 by using the domain name www6.v6address.com. At this site you can test web, telnet, and email, all over IPv6. For details, see the site. One facet of this is a dual stack version of whatismyipaddress.com (a site that currently supports only legacy IPv4).

There are both e-mail and telnet auto-responders. If you are on a text-only node (e.g. Linux or FreeBSD with no GUI Look and Feel layer), you can check whether your IPv6 is working by doing telnet to v6address.com. If you send mail to This email address is being protected from spambots. You need JavaScript enabled to view it.,">This email address is being protected from spambots. You need JavaScript enabled to view it., it will send mail back to you with the header records from your email as the body. If you have IPv6 email correctly configured, it will send the reply over IPv6. You can submit an email address, and the site will analyze the MX records for that domain name and let you know if they are correctly configured for dual stack e-mail. This helps a lot when you are deploying dual stack e-mail - otherwise you need a friend that already has this working to test your system against.
