IP Address Help

Thebug · 17 May 2008 at 18:26

Ok i need help giving my network devices there own ip.

I have a wireless laptop, wired desktop, and a synology NAS all getting there own ip automaticaly but sometimes my laptop decides to use my nas ip meaning i cant access my nas without changing the ip in my firewall.

This is getting annoying so i want to give both computers there own ip, so how do i do it?

Both computers running Vista Hp.

Thanks

Easy peasy.

Control Panel>Network and Internet>Network and Sharing Centre>Manage Network Connections

Open the connection and select Properties. Then double-click Internet Protocol Version 4>'Use the following IP address'.

Allocate it an IP within your routers IP range, fill in the Subnet Mask (found by opening a command window and typing ipconfig) and the Default Gateway (your routers IP address - 192.168.1.1/10.0.0.1/10.1.1.1 or whatever).

If you need to designate your ISP's DNS servers then you can usually find them through their website or Google.

Ok working ok on my laptop - but one more question - do i need to disable anything in my router ie: DHCP?

Cob · 17 May 2008 at 20:59

Nah you should be able to leave it enabled.

Although be consious of what addresses are being used as static and what range the DHCP is using. For example if the DHCP assigns 192.168.1.2 to something then a device with the same static address boots up there will be a conflict. not a huge deal but can be annoying

Also be conscious if you want to get online somewhere else with your laptop you'll probably need to enable the DHCP client again (obtain an IP address automatically). May be more advisable to give the NAS a static IP rather than the laptop, since the NAS won't be going anywhere.

You'd be better off setting your routers DHCP range to start from say 192.168.1.10 then manually assign the NAS an IP below that range and still have the laptop use DHCP. You could then choose to either leave the desktop with a DHCP assigned address or manually assign one also.

That sounds like a better idea.

Thanks will try it now

Most router DHCP servers will allow you to reserve an IP. So any time you add a device with a static IP, you add it to the reserved list and the DHCP server won't assign that number. No real difference from the method you're trying though.

As long as you avoid setting a static IP between the .02 and .10 ranges you should avoid having DHCP allocate it elsewhere. Unless ofcourse you have 10 dynamic IP's in the network too.

What router do you have? you should be able to reserve IP addresses for certain systems using a MAC address, i have it setup like this at home so my port forwarding works properly/

Netgear WPN824

Pretty sure i have got a reserve ip option in there - will there be any benifit using this compared to telling the dhcp to start at at say 192.168.1.8 like i have done?
