dhcpwindows-server-2003
I have a list of DHCP reservations, Server 2003.
I want to export (in all it is) a list of IP, MAC address.
I need the list for view: sorting\store in of DB for later Query, not for importing later. and therefore this command:
netsh dhcp server export c:\1.txt all
Not good for me, because I can not read the file (I'm only human …), there is another way to export or easy way to read this file?
(I do not care to write code to parse file but I could not understand how it is written).
Your router can indeed lease that IP address to another client once the lease expires if your machine is off or disconnected, and doesn't renew it. To guarantee you always get the same IP address, you'll want to make what's called a DHCP Reservation in your router (terminology may vary - see this question for details):
With DD-WRT firmware, you can find this under the Services section:
Although you can remove both from the server, it is not recommended to remove the DNS server part, because this handles the translation from server name to IP address.
Then of course, there is always the ability to have 2 DHCP servers running concurrently. Configure them the same, but make sure their scopes do not overlap. This way, you always have a fall back. But this is not required. You could entirely use the DHCP server from the router, which, in this case, is preferable.
What you want to do is as follows:
Make sure your server has a static IP address outside of the DHCP scope.
On your router configure the DHCP server to hand out IP's as follows:
- IP range with subnet mask that is free
- DNS Server1: server 1, your server's IP address
- DNS Server2: Either the one of your ISP, or 8.8.8.8 (google's DNS server)
Do note that there is a risk with this setup. If your server goes down, DNS will not be translated anymore. The client will still be using this DNS server until they get a new leash from the DHCP server, so the client needs to reboot until the server problems are solved.
This is not best practice, but for what you want it should do.
