changing of i.p address by the HDX?

David, I have not experienced this ip address phenomenon. I am using not the preset IP address, but my own configuration that works well in my home since I have other devices on the intranet.

I'm surprised at the speed of your ripping with the HDX, it does not sound right. The information says 7-8 minutes per rip on average and this is what I have experienced through 350+ rips, as well as, seen others posted and at my dealers.

The longer ripping at this time may be due to the fact that the HDX was performing a back/up while you were trying to rip. Check "system" and back-up settings to confirm.

The address may change if the HDX is set on DHCP. If you prefer this not to happen again, set the address as static, out of the your router DHCP range.

Your ripping time is way too short. As Gary said, it should take about 7-8 minutes per disk. Quite strange...

Its probably because your router (with onboard DHCP server) is not permanently on and the HDX was in standby.

(Remember if you turn off your router, the table containing all of the existing devices DHCP IP's on your network is usually lost and thus there is a protocol for re-enumerating this info).

If the HDX is off when you repowered the router, its original IP address(s) is still held on board (like a normal PC). Now, when you turned on your router all of the devices on the network in DHCP mode grabbed the next available IP address and carried on their merry way. Problem is, when you then power up the HDX its existing lease is still valid, so the unit tries to use the old addreses.

What happens next is that another device will probably complain that the (HDX's) IP is now already in use (due to the router being ignorant of the HDX still having a valid IP, when it was off), so after many milliseconds of shouting at each other, the HDX realises it needs a new IP address and asks the DHCP server for another...thus it can get a different IP address.

The two options are:

1) Some routers can be set to give out a specific address to the device in question, if you give the MAC address, see router documentation.

2) Set a static IP address for the HDX (and its front panel) using the supplied SETIP tool. Any devices requiring a static address must not be in your current DHCP range (this is standard network protocol for any network setup), thus you will need to change the DHCP range (see comment on reading documentation below). Ideally the unit should be used in DHCP mode where possible.

I strongly recommend you (and anyone else wishing to set the HDX to a static IP) to read all the documentation in the Public->HDX section of the naim download site here, before attempting this:

Thank you Paul

Some carefull reading and inwardly digesting required to get my head round this! A very full and succint explanation.

David, interesting reading. I think that DHCP was chosen as the standard as it didn't require any set-up. From conversations I've had with NANA the static really is the preferred method so you don't run the risk of having what happened to you occur on a regular basis. This however as stated above requires some set-up using the DTC software.

I have numerous devices in my home using DHCP and while for the most part it's fine even when devices are turned off or the router goes out in a power outage the HDX having 2 IP addresses for the front and back panels as shown in the diagram from the download can create this problem.

It takes only a few minutes to set up but you need some familiarity with IP protocols and how to obtain the DNS, Net Mask, and Gateway from either your router or from a computer connected to your router. Once this is obtained the set-up is straight forward using the static tool on the DTC.

If you are not familiar or do not have a friend or IT person to assist you, I'm sure that the people at Naim would give some assistance. Because of the set-up issue and calls it would generate, I'm sure that this is the reason for using DHCP as opposed to static. Makes sense.

David, this will tell you how to identify the information you need to do the set-up. The only other information is you DHCP range as the HDX must be programmed "outside" of the DHCP range and you should give the HDX 2 addresses which are consecutive in the last 3 numbers.

Thank you Gary,

The HDX files referred to by Paul have dire warnings:

Incorrect settings can result in the unit failing to work correctly and it may be
necessary to return the unit to Naim for recovery.

I will tread carefully

To be clear here:

Only SETIP tool should be used to change HDX/NS01/2/3 IP addresses, not DTC (the older V1 DTC did allow you to do this for NS01 and 2, as they have no front panel).

To be safe ONLY use SETIP tool to change from/to DHCP/Static.

Also, anyone using Desk Top Client should not be using a DTC older than 2.0.5.1122 anyhow (see DTC Help->About Desk top Client menu)

Setting a static IP in the DHCP range is definitly a nono in network-land.

Sorry, you are correct, I meant to put "set-up IP tool". David, it is found using your computer start menu in case you have gotten confused.

You could set a reservation in the dhcp tables for the hdx

see note 1) in my first post above, I was a bit vague I admit.

I have been the proud owner of a new HDX as from Xmas eve.... This has been a very nice system to use. Ripping discs has been taking approx 3 minutes per disc. I have now ripped 400 discs so far.. One or 2 discs in the last 20 or so have been taking rather longer, long pauses between successful AMG data look up and slow ripping. I wonder whether this is a feature of a hard disc getting “fuller”.
Yesterday I found that I could no longer access the HDX via desktop client or via ip address. I restarted the HDX and router. No joy.

Newer HDX units have a slightly faster disc loader mech, which takes a little bit less time than the previous one to rip a Compact Disc. They cannot be fitted to older units.

However, the problem you indicated about the delay incurred before ripping sounds to me as if your internet connectivity had been interrupted, whereby the unit would try to access AMG first (no luck due to lack of outbound connectivity), FreeDB second (similarly no luck), and the internal cached copy of FreeDB last (successful if found).

I always recommend static IPs for permanent installation, by the way–depending on your router, this inside (LAN) address can be independent of whatever scheme your ISP uses to assign outside (WAN) addresses.

Shouldn't make any real difference if you use DHCP or assign a static IP to a unit on an IP network. Only real difference is if you need to use a IP address to connect to it and then having a static can help with that. But, if all you are doing is sourcing data from the device, then DHCP or static should make no difference.

AV, most DHCP servers should ARP for addresses before assigning then, so you are usually safe assigning within the DHCP pool range. Though, outside is safest.

Apologies, I missed that.

yes they "should"...

But hey, I'm certainly not going to argue with you of all people on networking protocol Roy!

Precisely. In an environment where one needs to know that a device is exactly at the address where it is purported to be, this seems to be the most intelligent approach.

I don't understand why people fight for the right to DHCP, really–reminds me of life in a caravan.

Just a brief note to remind eveyone that the HDX should only be powered up after it has been connected to a working ethernet environment to avoid default IPs being established. So connect to network, then apply power.
