Host names and mac addresses?

**WhiteD3** · 5th February 2012, 07:29 AM

I've got a dozen or so devices on our home network; some of which are permanent while others (wireless) come and go.

Every now and again the belkin modem/router gets reset and so all the IP addresses are reassigned. This is an issue for a few of the devices that I access remotely via IE, namely the CCTV recorder, because the host name (for most of the devices on the LAN) do not appear in the router's DHCP client list.

I've noticed this is the case for a few other devices on the LAN too.

Why is this so?

I can get around this by looking up the MAC addresses then cross referencing to the IP address, but this seems to be a redundent way of doing things.

Does your router in, say, LAN Setup, allow you to do Address Reservation?

Mine does so I assign an IP address to a MAC address so every time the router is rebooted, certain devices always end up with a specified IP address.

Thanks Ron. That what I need but my router doesn't do it. It'll allow me to do mac filtering but that means turning off DHCP and manually assigning IP addresses.

What's the brand and model of your router?

Mine's an older Netgear WNR2000.

can you set each device with a static IP so each devices retains its IP address. Most network devices have this ability.

I can but I'd rather not. It would mean having to assign an IP every time one of my kid's mates come around with their wireless whatevers.

i guess buy a new router that allows reservation of ip address assigned to MAC ?

if your router wont do it then i guess you are stuck with static or dhcp.
Apparently you can force a NIC to run both dhcp & static by hacking the registry but I have never tried it.

You can still assign static ip's to the devices whilst running your router as a dhcp server. For example you have a windows 7 media pc (as I do) set this up with a static ip using the network properties in windows 7, make sure the gateway and subnet are correct then give it an ip, make sure this ip isn't used by any other device first. You can use this method for any devices that you don't want the ip to change. This way you still have the flexibility of both dhcp and static
