hdx changes IP-address

Posted by: kingsfan on 27 October 2011

Hello Naimes

 

Why does my hdx change IP-address? It has now happened 2 times in three years. it´s always the last number that is different.

I would guess because it's set to DHCP and requests an IP address from your router whenever it is rebooted (or its DHCP lease expires) - your router will usually give out the same IP address but if *IT* has been rebooted then it may not...

 

This is absolutely normal DHCP operation.

As Phil says that is normal DHCP behaviour. You should be able to force your DHCP server (probably on your router) to always supply the same DHCP address.

Hi Hans, as others say its likely the HDX is getting its address from a DHCP server. For many typical home or small private networks (class C) then the first three digits define the network address and stay the same, and the final number defines the client host (HDX) address on that network and can change to any valid value. (sometimes the final number can be a combination of network and host address, but that's only if the final digit of the subnet mask is not 255).
You don't need to worry about this normally, but you did ask ;-)

My Netgear router allows you to allocate an address to a particular device (ip address reservation) my own network I have allocated 192.168.0.100 for my HDX - which means that it will always have that address and typing or bookmarking http://192.168.0.100 into the address line of internet explorer of other flash enabled internet browser will open the HDX web interface so that you can control it from a PC or Mac. Hope this helps

Yes Green, this is the way to go on small network.

Greensticks, indeed, a good example, so in your case the network assuming subnet mask of 255.255.255.0 your network address is 192.168.0 and your host address on the network is 100. Therefore any device with 192.168.0 as its network can see any other device on that network such as 192.168.0.50.
To see devices on another network such as 192.168.100.50 you would need a (proper) router to route between network addresses. For simple home networks you only need one network address so that's why you keep the he first three digits or the network address the same for all connected devices.

I suggest you use the Naim IP Tool to set your HDX a static IP. This similar to reserving an address but done on the HDX end not the router. You need to use an address outside the routers DHCP range....I use 210 for HDX and 211 for front display. Works great Before you change...you can copy all of the subnet data down by reviewing status screen and just replicate in IP Tool. Really easy
