Is It True That Verizon Wireless Has Run Out Of IPv4 Static IP Addresses As Of June 30th, 2017?

There has been so much FUD lately about whether or not Verizon Wireless has run out of IPv4 Static IP Addresses. The root of the problem is that Verizon Wireless issued a formal, published statement on March 8th, 2017 letting their clientele and partners know that Verizon would stop issuing any new IPv4 Static IP addresses on June 30th, 2017 due to lack of availability. See that announcement here.

Since many businesses and government agencies that use the Verizon Wireless network for M2M communications absolutely require IPv4 Static IP Addresses and cannot make the move to IPv6 addressing, this came as a shocking wake up call–even though since the early 2000s networking professionals have wrung their hands about the fact that the addresses are finite and would some day run out. So is June 30th IPv4 Static IP Armageddon for users of the nation’s top network? The answer is “no.”

Since the March 8th announcement, several Verizon Wireless sources have confirmed that large blocks of IPv4 Static IP addresses have been located, and are available. That said, like any finite resource, how long they last is directly related to how quickly they are consumed. Go figure. The end is nigh, although the exact date is now unclear to anyone, I believe.

What is the antidote to this problem? A Private Network is. Verizon Wireless and other top-tier carriers are absolutely shepherding their clientele to the security of Private Networks–which also have enough IPv4 Static IP Addresses for today and the future. In addition, innovative, client-centric companies–like mine–have also invested in ways to ensure that their clients do not lose sleep at night about the IPv4 Static IP address crisis. At USAT Corp., we do that by ensuring that ANY client large or small, has access to a Private Network without all the expense, time investment, long deployment schedules and technical expertise that has historically kept the barriers to entry very high. Read about how we do that, here. On a different front, there are also emerging software defined networking options that are very interesting and worth reading up on as they bring networking into a “GUI in the Cloud.”  In closing, savvy members of the M2M/IOT ecosystem that use the public carriers networks for data transmissions AND require IPv4 Static IP Addresses have been gifted a little more time to plan on what their next move will be. Time to buckle down and do the research and make some proactive decisions.

As an active adviser to your wireless communications initiatives, USAT Corp. has information to share:

*IPV4 & IPV6 INFORMATION*
 
VZW recently announced that it will stop issuing new public static IPv4 IP addresses on June 30th 2017. USAT has analyzed how this will affect our critical infrastructure clients and an initial summary is below:

  • If your organization’s communication devices are currently sending data on a Verizon private network, you will not be affected by this change.
  • Any existing IPv4 public static IPs currently in use will continue to operate as usual after June 30th 2017.
  • Any devices activated on the VZW network after June 30th MAY NOT be assigned an IPv4 public static IP address. USAT has received no guarantees that exceptions will be made.

 
IN ADDITION, PLEASE ALSO CONSIDER: that if your organization has reserved IPv4 public static IP blocks but do not have the associated IPs assigned to an active device on the VZW network, it may be in your best interest to activate them before June 30th, or VZW will have the right to reclaim those unused IPs from your organization.
 
Below find two statements from USAT’s key manufacturer partners about IPv6 support for their product lines post-June 30th. In both cases, the news is good:

 
If you have any concerns about a specific wireless gateway/router or if you are questioning whether your application requires a public static IP, please contact your USAT Corp. sales account manager or respond to this email.
 
*SIERRA WIRELESS FIRMWARE—IMPORTANT ACTION REQUIRED—UPGRADE TEMPLATES TO 4.7*
 
It is important to note that all new devices in the GX450, RV50, and ES450 product lines from Sierra Wireless are shipping from the factory with 4.7 pre-loaded. Once a device has 4.7 on it, the device cannot be downgraded to an earlier firmware.  In preparation for new deployments, USAT recommends that all current users of the GX/ES and RV families upgrade an existing unit in their stock to the latest firmware and validate that all of their configurations work with their solutions. 
 
More information about the ALEOS 4.7 firmware update can be viewed here: http://usatcorp.com/key-points-sierra-wireless-aleos-4-7-0-firmware-release/

*SIERRA WIRELESS End Of Sale (EOS) ANNOUNCEMENTS*

 
–All GX400s will EOS on April 30th 2017 with the last ship date set for 12/30/2017.
–The AT&T LS300 will also EOS on April 30th 2017 with the last ship date set for 12/30/2017.
–Please note the VZW LS300 is still actively in production and EOS has not yet been announced.

Archive-October 2016-Tech Bulletin–Mirai Advisory And New Wireless Network Products MG90

Our mission is to keep you informed about information key to the success of your organization’s wireless data initiatives. Below you will find an overview of important facts about the Mirai virus. Near the bottom of this email, you will find information about new products that you should be aware of in the wireless data communications space.

Mirai Summary: A new Trojan virus called Mirai is in the news.  Mirai is targeting Linux servers, M2M and IoT devices, including cellular gateways and routers, but mainly cameras and DVRs, running Linux-based firmware, for the purpose of nefariously engaging these systems as part of a large botnet used to stage Denial-of-Service DDoS attacks designed to disrupt access to web properties. (More info: https://safeum.com/blog/2014-mirai-trojan-is-the-next-big-threat-to-iot-devices-and-linux-servers.html) Runaway cellular airtime usage can be a result of infection. In the world of wireless networking, any device that runs on Linux is susceptible. PLEASE NOTE USAT CLIENT BASE: Critical infrastructure clients who are on private networks run a reduced risk of infection.

How Infection Happens: Mirai infects devices via brute-force attacks on the Telnet port, exploiting a “black hat” list of default password credentials, taking advantage of instances where device owners have forgotten to change the built-in default password to a secure password. Critical infrastructure clients who are not on private networks but who have implemented complicated passwords (like what the USAT DevProv+ service facilitates) and instituted other basic security functions like “white lists” and “black lists” are unlikely victims. If you have not or suspect that a user within your organization has not changed the default passwords on the devices attached to your corporate network, then it is important to implement secure passwords now in order to avoid operational ramifications as well as possible financial charges due to data consumption overages.

How To Diffuse Your Risk & Treat Infection: Good news: even if your device is infected, restarting the device and changing the password is an effective treatment. Sierra Wireless, a world leader in the manufacture of cellular gateways was the first to issue a technical bulletin detailing the threat of Mirai to the M2M/IOT ecosystem. Please refer to the steps that they suggest to secure devices here: http://usatcorp.com/action-required-sierra-wireless-technical-bulletin-mirai-trojan/.  The Department of Homeland Security also very recently issued an informative publication on defeating Botnets here https://www.us-cert.gov/ncas/alerts/TA16-288A. In addition to the advice issued on the DHS link, best practices dictate that if you are a user of cellular routers and gateways, make sure that devices in your network are running the latest firmware.
Please feel free to respond to this email with additional questions or concerns about the Mirai virus.

4G Cellular Modems For US Cellular–Sierra Wireless AirLink GX450 & ES450

For many years, users of the US Cellular network lacked options when it came to selecting a cellular 3G/4G modem, gateway or router for wireless data acquisition and remote monitoring applications. For organizations that were using the US Cellular network, the lack of “certified” devices was a potential barrier to launching M2M or mobility projects using a public network backbone. Well, the wait is over. For those clients who have been looking for a reliable US Cellular cell modem option for in-vehicle usage or for SCADA, distribution automation or other types of industrial automation, the wait is over. US Cellular has certified the Sierra Wireless AirLink GX450 and the ES450 for use on the US Cellular network as of July 15th, 2015 and the devices are available and shipping now. See them both below.

Tech Note: Required configuration is North America Generic and ALEOS 4.4.1 or later is required.

Sierra Wireless Airlink GX440 End-Of-Life

It is official: Sierra Wireless will cease production of the AirLink GX440 in that not too distant future. The Sierra Wireless GX440 is sunsetting at the end of 2015. Last buy for the GX440  will be Dec. 31st, 2015. Last shipment will be June 30,  2016. Why the six month differential between last buy and last shipment? Because Sierra Wireless is most likely going to allow phased purchase orders is our interpretation. The replacement product for the GX440 is the GX450. The time to start planning for your company’s migration to the GX450 is now. For a summary description of the differences between the GX440 and the GX450, visit this link.
