ZoneEdit Free DNS Service

ZoneEdit provide free DNS services that allow you administer a website for no cost. They also offer additional nameservers for a subscription. The adding of these servers is supposed to increase the visibility and "up-time'' of your website.

Part of the ZoneEdit Terms of Service as it relates to the surrender of  information.
ZoneEdit administers nameservers and keeps a record of the domains that are using that service. It does this for billing purposes. If you are using the free service you are not billed and as such there is no need to use your real name and address.

DNS Services

This is my post that explains my use of DNS services and how I selected the one that I used.

Prior to my website rebuild I was using the services of ZoneEdit. I still have a ZoneEdit account but my website is no longer resolved by the service. I retain it in case that I wish to re-instate the website.

I subsequently obtained a Cisco Residential Gateway and notice that I can do similar operations with that.

DynDNS.com are partnered with Cisco and offer DNS services that can be configured in their routers and Residential Gateways. This subscription service can be used to host a website on your residential Internet connection.

DOCSIS Cable Modem Specification

DOCSIS - Data Over Cable Service Interface Specification

I have recently upgraded to a DOCSIS 3.0 Residential Gatway.  I think that my previous cable modem was DOCSIS 2.0. It is not clear whether it is just the speed capabilities of DOCSIS 3.0 are the major reasons for the upgrade - trials with download speeds of 1.5 Gbit/s and upload of 150 Mbit/s based on DOCSIS3.0

The implementation of IPv6 is the area of interest for me and its implications for system security.

Quoting from the WikiP page:
DOCSIS 2.0 was released in December 2001. Most recently, the specification was revised to significantly increase transmissions speeds (this time both upstream and downstream) and introduce support for Internet Protocol version 6 (IPv6). This version, DOCSIS 3.0, was released in August 2006. 

My concerns about the loss of anonymity

As the DOCSIS specification and implementation has the potential of much more precise addressing it would appear that the technology would allow individual devices to be connected to the Internet directly. The use of a router, as in the days of IPv4 will be less of a requirement.

The fact that Cisco name their current modem/routers "Residential Gateways", to me, is an indication of this. However, as we are still in a largely IPv4 world the "gateway" assigns local LAN addresses to individual devices connecting to the Internet through it. The way that I see this developing is that this eventually will not be the case and the gateway will connect your device directly to the Internet with no NAT (Network Address Translation)

Splashtop Remote Desktop

Splashtop Inc is a privately held software company based in San Jose, CA

What Splashtop Inc. say about their products:
A computer with the Splashtop Streamer can receive connections from any device running Splashtop Remote Desktop , FileHound , Splashtop Remote Browser , Splashtop Whiteboard , Splashtop CamCam , Splashtop XDisplay , Splashtop Touchpad or Splashtop Presenter applications.

This is an Asus thing (in that some Asus computers come with this installed or it is promoted when you purchase and use an Asus tablet). Remote connections can be made using other vendors hardware and software. However, it does make a compelling case for Asus tablets and other computers, not just Asus, running the Splashtop software.


I have run the Microsoft Office suite on an Asus Prime and it was fully functional. You can even use Splashtop remote to control an Adobe or Powerpoint presentation.

The Asus Prime comes with the Splashtop Remote Desktop pre-installed. This prompted me to download (and purchase)  the Desktop app for my Blackberry Playbook.

MARECS B

I was responsible for the design and manufacture of L-band power amplifiers for the MARECS communication satellite.

MARECS B was launched into Geosynchronous orbit by an Ariene launch vehicle and is in stationary orbit above the Pacific Ocean.

MARECS B followed MARECS A, the subject of the video above. I was proud to be part of the team that pioneered mobile communication systems.

My part of the design and manufacturing process was the development of MMIC modules, manufacture of Space hardware in a clean-room environment, testing and tuning, multipaction proving and team leadership.
