June 6th 2012: World IPV6 Day

Just a year ago, we wrote about World IPv6 Day and the need to transition from IPv4 to IPv6. World IPv6 Day last year was a day to test IPv6 enabled websites. Today we revisit that day, but instead of it just being a “test flight” day,  June 6th is the Official IPv6 Launch Day. Today, organizations worldwide including (but not limited to) Facebook, Cisco and Google will make the official switch to IPv6.

We are proud to announce that we have progressed in the transition to IPv6. Two of our name servers, ns1 and ns2, are currently IPv6 enabled and anycasted in over 7 locations. They are capable of handling quad A records (AAAA). We plan to have ns3 enabled within the next few months. There is still a long way to go and by enabling IPv6 support, we are keeping pace with the Internets ever expanding audience and growth. Our update API will accept quad A (AAAA) updates within the next month.

Check out the screenshot from the member’s section. Click the Hosts/Redirects Tab and then click Add Host (located in the left navigation) (Note: IPv6 is only available on Plus Managed DNS)


Why is the transition to IPv6 so important?
To access the Internet on an Internet enabled device, the device needs an IP address. Every website, computer, mobile device, (even some light bulbs) NEED an IP address in order to access the Internet.  IPv4 addresses are only 32-bits long, meaning there is only a total of 4.2 billion IP addresses available. Well, since everyone and their mother (and grandparents) are on the Internet, those 4.2 billion IP addresses are quickly running out. In short, we need MORE SPACE!

So, this is where IPv6 comes in to play. IPv6 addresses are 128-bits long and there are a total of 340,282,366,920,938,463,463,374,607,431,768,211,456 (yea, that’s over an UNDECILLION) possible IP addresses.

In short, you could say that because of the implementation of IPv6 the growth, evolution, and future of the Internet is secured.

We are here to help you during this transition. You can now add and modify IPv6 quad A records to a host.  (Quad A records are only available on No-IP Plus Managed DNS)

Tech Term Definitions for the Non-Tech Person

Sometimes, we use tech terms and explain things in a way that a not-so-technical person may have a hard time understanding. This blog will try to explain those terms in an easy to understand way. Enjoy!

DNS Resolution (Resolving) - During DNS resolution, a DNS server is contacted and the IP address of the URL you are trying to reach is returned. So, your computer asks the DNS server, “what is the IP address for yourhost.no-ip.com“, and the DNS server replies with the current IP address, which connects you to the correct website. This is the bread and butter of the Internet and how it works.

Delegation- Delegation is where you are assigning a group of name servers to be responsible for a domain name.  During the resolution process, the name servers that are assigned to a domain are directly asked what to respond with (what IP address) for a DNS request.

Port Forwarding- If you have a router at home or your office, you will need to forward ports in order for outside traffic to get into your network. Think of your router as being a huge electric fence or wall, with a few doors or openings. This electric fence or wall serves as your barrier and security blanket from the scary outside Internet world. Your router comes preconfigured with a few of those doors (or ports) open to let you access the internet, but the others are closed tight. So, in order to run a mail server, game server, access your computer remotely, etc you will need to open an extra door or two in your router in order for the outside traffic to get inside. This is called Port Forwarding.

IP Address- An Internet Protocol Address or IP address for short, is like your computers phone number. Without it, your computer wouldn’t be able to connect to the Internet. Every computer, tablet, smartphone, and the internet-enabled device has its own IP address (even some light bulbs have an IP address these days).  An IP address consists of numbers and periods (

Static IP Address- A static IP address is one that doesn’t change, it is assigned to you by your ISP (Internet Service Provider) and often costs extra money. A static IP address is YOURS and will never change (unless you cancel the subscription)

Dynamic IP Address- A Dynamic IP address is one that is NOT static. It changes from time to time. If you are unsure if your IP address is static or dynamic, chances are pretty high that it is dynamic. They are more cost-effective for your ISP.

Hostname vs. Domain Name- A hostname is the beginning part of the domain, which usually consists of www. Another word for a hostname is a subdomain.


With our No-IP Free Dynamic DNS service, you choose one of our free domains, (no-ip.org, systes.net, no-ip.net) and you use a host or subdomain on it. You are essentially sharing the no-ip.org (or whatever domain you choose) domain with everyone else that uses that domain, but you just have your own little space on it. That little “space” is called your hostname.

In comparison, with our No-IP Plus Managed DNS service, you register your OWN domain name, and then you use the subdomains or hosts on that domain. No one else will be able to add subdomains or hosts to this domain because it is yours. Get it?  (Example: www.mydomain.com and the hostname would be something like…. myhost.mydomain.com)

Redundant- This is a term to explain that the network is guarded against downtime because the domain or hostname that you are using is hosted on many different servers that are located in various locations across the globe, not just one. So, if you are located in Los Angeles, and there is an earthquake, your website will stay live even if the servers located in Los Angeles are not online.

URL- Abbreviation of Uniform Resource Locator (URL) it is the global address of documents and other resources on the World Wide Web. (www.no-ip.com or yourhost.no-ip.org)

HTTP- Hypertext Transfer (or Transport) Protocol, the data transfer protocol used on the World Wide Web. The secure and encrypted version of HTTP is HTTPS. If you are browsing the internet and want it to be secure, add the S. Make sure websites that you enter passwords and private data on have the HTTPS. Without that S, you’re not browsing securely.

F-Secure Releases Warning About Olympics-Themed Malware

F-Secure released a statement earlier today warning of an Olympics-Themed malware attack that is being sent via email.

Excerpt from the F-Secure website:
“The PDF exploits CVE-2010-2883, which affects older versions of Adobe Reader and Acrobat. A typical PDF exploit will launch a clean decoy as part of its attack, and in this case, the decoy is a copy of the London 2012 Olympic schedule circa October 2010. The original source PDF can still be found online at: london2012.com.”

What should you do? Well for starters, take 2 minutes and update your Adobe software.  Also, as always never open links or attachments in emails from people that you do not know.  Always be sure to double check links and beware of phishing scams. Check out this article for more information on safeguarding yourself online: Go Phish! Top Tips on Protecting Yourself From Phishing.
