<a href="http://169.254.0.0/16">169.254.0.0/16</a> is the DHCP autoconfigure address. Any host that tries to get a DHCP address, but fails, will pick a random address out of that network. The idea is that if everyone uses that network, you can still have communication between hosts.<br>
<br>If you want to go that route (pardon the pun) then you could always give your Mac a second IP address of <a href="http://169.254.1.1/255.255.0.00">169.254.1.1/255.255.0.00</a> and it will be able to talk to the HDHomeRun box... as long as you know the address of the tuner. <br>
<br>Alternatively, set up a DHCP server to serve addresses within your subnet. You can safely run statically addressed machines and DHCP machines together. Configure your DHCP server to only use a small range of hosts that won't conflict with your static addresses. The static machines will work, the DHCP machines will get their address with DHCP.<br>

<div style="word-wrap: break-word;">I am wondering how I can connect my Mac to a device over ethernet, when I have no control over the device's IP address.<div><br></div><div>I recently purchased HDHomeRun, a dual TV tuner that connects via ethernet. The idea of it is to be able to stream video content to any machine on your network.</div>
<div><br></div><div>My network has static IP addresses, so just plugging it into the hub and searching for the device does not work. I understand that it is a DHCP client. There is no documentation with the device, such as a default IP address if one exists.</div>
<div><br></div><div>I will only use the video on one machine at present, my Mac. Wikipedia indicates that the device "will also work via an <a href="http://en.wikipedia.org/wiki/Link-local_address" title="Link-local address" target="_blank">auto IP</a> address if no DHCP server is available". Instructions meant for Windows (different document) talk about assigning an IP address of <span style="font-family: Verdana; font-size: 10px;">169.254.x.x to the network interface.</span><div>
<br></div><div>I am far from clear on how that works. If the NIC I use to attach the HDHomeRun has such an IP address, does the HDHomeRun know to configure itself with a similar address? The Mac's network preferences GUI allows 4 choices: DHCP, DHCP with manual address, BootP, and Manual. None of these seems to work.</div>
<div><br></div><div>I can't even be sure if the device works - but LEDs come on.</div><div><br></div><div>Does anyone have suggestions, other than changing my entire network to DHCP? Can you have some nodes on a network get addresses by DHCP while others are static?</div>
