If one looks closely, one might happen to notice that<br>
SD is now front-ended by cloudflare.... (which uses<br>
DNS in a way that the really old firmware was vulnerable<br>
to).<br>
<br>
As I recall, SD had run into the bug some time ago<br>
(and was why newer firmware already existed to<br>
resolved it(*); it was even in the changelog for the<br>
early 2015 firmware releases)), but had widely rolled<br>
out their own load balancing and failover solutions<br>
which only returned one IP address. Cloudflare<br>
does things differently.<br>
<br>
btw, for the record, the latest firmware on SD's<br>
download pages is now 20161107 (with a suffix 'b'<br>
for the CableCARD firmware), but if you download<br>
it from the web site (as you stated) you will get the<br>
latest.<br></blockquote></div><br></div><div class="gmail_extra">Nick here from Silicondust...<br><br></div><div class="gmail_extra">Confirming, we found and fixed a bug in the firmware a few years ago relating to DNS handling.<br>For HDHomeRun PRIME units it affects units running 20130117 or older firmware.<br>For HDHomeRun DUAL units it affects units running 20141124 or older firmware.<br><br></div><div class="gmail_extra">The easiest fix is to unplug the WAN port of your home router so the old HDHomeRun firmware is happy, then upgrade it to the latest firmware (20161107b for PRIME and 20161107 for DUAL).<br></div><div class="gmail_extra">The direct firmware download links can be found on our website under Downloads, Linux.<br><br></div><div class="gmail_extra">We are beefing up our server infrastructure... we now use CloudFlare for the first level.
