What’s the deal with DNSChanger Malware?

The FBI will be shutting down the temporary DNS servers that they set up to support Internet users that were compromised with DNSChanger malware. Anyone still using those DNS servers will be unable to resolve host names, which will effectively render them unable to do pretty much anything online until they clean up their infected system.

On November 8th 2011, the FBI, in conjunction with NASA-OIG and Estonian police, arrested several criminals operating under the company name “Rove Digital”. Rove Digital had been distributing DNS changing viruses (TDSS, Alureon, TidServ and TDL4). They then routed victims through their own DNS servers in order to direct traffic to junk ads. They infected around 4 million users, and made a reported $14Million before getting shut down.

With such a large number of compromised users relying on Rove Digital’s DNS servers for their Net access, the FBI decided to temporarily leave the DNS servers up and running to give people time to clean up their infected systems. Because people have been slow about cleaning up their computers, the FBI extended their original March deadline to Monday July 9th.

If you would like to verify that your computer is clean, you can go to for a list of safe sites that you can use to check. Should you find that you have a compromised computer, they have good resources available to help you clean up your system.

World IPv6 Launch

Today is the day many companies and organizations permanently enable IPv6 for their products and services. This is a big deal.

We’ve had all of our major public servers accessible by both IPv4 and IPv6 for some time, and continuously since World IPv6 Day last year. We’ve also been assigning IPv6 networks by request to customers with routers and network gear capable of supporting it. We’d love to assign more, but although enterprise-grade equipment and every major computer operating system supports IPv6, support in consumer-grade equipment such as DSL routers has been in a chicken-and-egg limbo for years.

So what’s the big deal?

The Internet has run on the IPv4 protocol since September, 1981. An IPv4 address is a 32-bit value, which provides around 4 billion unique IP addresses. Even though changes have been made to the allocation and usage of this space, from replacing the original classed network system with CIDR to routing schemes like NAT, it was never really designed or intended for an rapidly growing public Internet, and it’s clearly at the end of its road.

IPv6, which has actually been around for longer than you might think, is the next generation of Internet addressing. Will it ever fully replace IPv4? That’s unknown but the days of freely allocating more IPv4 addresses are at an end.

IPv6 uses a 128-bit address and provides a vastly larger number of unique IP addresses. Large enough to handle 4 billion unique organizations each with 4 billion unique clients each with their own 64-bit address space, itself 4 billion times larger than the entire IPv4 address space. IPv6 provides the room to create and implement advanced networking features like auto-configuration, efficient routing, and simplified renumbering.

What can you do to help move us further away from IPv4?

Talk to your Internet and/or hosting provider about IPv6 and ask about their deployment plans.  Ask them to publicly comment or announce their plans. Talk to your IT department and ask the same questions.

Welcome to the production Internet!

VMware Certified Professional

VMware Certified Professional Addition

I am very proud to announce today, February 7th, 2012, Ben Tucker passed his VCP test to become the third VMware Certified Professional employed by ipHouse (25% of our employees now hold VCP certificates).

From VMware’s VCP site:

This industry-recognized certification requires completion of a VMware-authorized training course and hands-on experience with VMware technologies. Achieving the VCP certification confirms that you have the education needed to successfully install, deploy, scale and manage VMware vSphere environments, as well as the skills obtained by a minimum of six months experience with VMware infrastructure technologies.

ipHouse employees hold many VMware certifications:

  • 3 have VCP certificates: Mike, Nick, and Ben
  • 2 have VMware Technical Sales Professional certificates: Ben and Nick
  • 7 have VMware Sales Professional certificates: Aileen, Alex, Andrew, Ben, Dan, Mike, and Nick

This means that ~60% of ipHouse employees are certified in VMware products with 3 employees holding multiple certifications.

What does this mean to you?

ipHouse employees can help design a virtualization solution for your business whether it is a single server web site to a multi-server Microsoft Remote Desktop Services solution and everything in between. Look at our vmForge offerings and give us a call at 612-337-6320 and let us help you.

IPv6 – Tech Talk with customers

Last month there was a little concern in the general media about the Internet running out of IP space and some customers contacted us about their concerns. We love energetic customers with questions.  Below is one of our customers’ comment and question:

“Dice predicted that IPv4 IPs would be completely allocated in the next 18 months.  Obviously (if this is true), they are interested in having people know something about IPv6 so they can have such expertise in their job exchange.

Do we as users of ipHouse need to be concerned about hardware, software, other implications of this — DSL, DNS, etc., etc. …”
