Dynamic DNS

Best Free Dynamic DNS Solution

Dynamic DNS

When DynDNS stopped providing free Dynamic DNS services I was left searching for a solution. I found NO-IP.org which I used for a few years, but got fed up with having to login every month to re-activate. So I found a solution that provides that, before I tell you about it. Let me list a few services and the pro's and caveats I found with them.

Windows Server Disable TLSv1.0

We all know by now that TLSv1.0 is broken we must disable it to protect ourselves from this vulnerability, here are the two registry key's that need to be created to disable TLSv1.0:

Launch RegEdit and navigate to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\"

In the "Client" & "Server" key and create a DWORD (32 bit) entry and call this "Enabled" and set the value to 0, also create a DWORD (32 bit) entry called "DisabledByDefault" in both "Client" and "Server" Folders/Keys.

"Enabled" - Disables TLSv1.0
"DisabledByDefault" - Advertises that the server can or cannot accept TLSv1.0

Auto Reboot Modem or Router

I previously posted a URL to remotely reboot your modem, however once I upgraded my modem I realized I had no way to remotely reboot this device, not via a web interface or curl command. So I took to the internet and found a couple device that would do what I needed. Essentially these devices ping a IP or domain name and reset power to the plug the modem is plugged into automatically if the ping fails. Most of these plugs can be controlled via web interface or mobile app, they also auto-reboot if ping fails.

Here is a list of them:

1) AVIOSYS International IP Power 9255 (Single Outlet)

Pros:

• Available in 5 global plug formats

Cons:

• No firmware updates since 2012

2) 3GStore Remote Power IP Switch (Single Outlet)

Pros:

•  Built in 10Amp Fuse
• Specify Ping Interval

Cons:

• Unable to Specify IP to Ping
• Firmware update must be made through iOS or Android Application, not web interface.

3) 3GStore Remote Power IP Switch (Dual Outlet)

Pros:

• Specify Ping Interval
• Specify up to 5 internal or external IP or Domain Names(ex. google.com) to Ping
• Specify reboot order(Plug 1 Only. Plug 1 First Plug 2 after specified time)
• Built in 10Amp Fuse
• Works with google talk

Cons:

•  Firmware update must be made through iOS or Android Application, not web interface.

4) Ambery IP-P2 (Dual Outlet)


Pros:

• Specify Ping Interval
• Specify IP to Ping
• Specify reboot order(Plug 1 Only. Plug 1 First Plug 2 after specified time)

Cons:

• No firmware update since 2012

5) ORUIBO 2200W GSM Remote Control Power Adapter

Pros:

• Reboot remotely by sending SMS or calling device.

Cons:

• No ethernet/wifi interface(not a network device)
• May have to use a adapter to plug it into your outlet, however once plugged in any plug can be plugged into it as it is universal.

Now I have to decide which one to purchase, once I do I will provide an update. These device can be  found on eBay or the manufacturers website.Thanks for reading and feel free to chime in and let me know if there other devices you know of. I thought about using a digital timer reboot the modem once a day or so but I think this would be a waste and could shorten the lifespan of the modem.
