DHCP and static ip simultaneously, one nic ?

[sillik]

DHCP dynamic ip and static ip simultaneously, one nic ?

Is it possible to use DHCP dynamic ip and static ip in one nic at the same time ?

Like in xp via regedit ?

Is it disabled to use them simultanously in win7, one nic?


Google is full of "alternative config" suggestions, but they aren't what i'm looking for.
(since it is for the "if DHCP isn't available" situation)

Is there really a need for that?

 

[sillik]

We'll, i'll save 20bucks, if i don't have to buy another nic and cable for it.

 

[mckillwashere]

Sorry about the long response time. I was just asking is there any real need for having two ips? If you are trying to use two separate networks you can always assign the info for both networks on the advanced page like you would do the the XP trick.

 

[sillik]

Yes, 2 seperate networks, same card. But when "obtain ip automaticly" is on, i can't add static ip's from advanced page. (add ip button is disabled, due DHCP in use)

So it leads back to my orginal question, is it possible like in XP or is that "trick" disabled in win7?


Starting to think, maybe it is just better to get that another nic.

 

[mckillwashere]

Why dont you just set two static ips, and completely eliminate the need for dhcp?

 

[sillik]

As i work at home, removing DHCP is not an option.

I allready bought that another NIC for the other network.

It would be nice to find some official info, if microsoft has disabled that dhcp & static ip trick simultanously in newer windows versions for future reference.

 

[mckillwashere]

Why is it not an option? In ip address is an ip address regardless of were it is obtained from is it not? All dhcp does is assighn the IP address, if you manually set the Ip address it bypasses the need for DHCP. You can set multiple gateways and multiple IPs under advanced options. So please tell me the factor I am missing here.

 

[sillik]

Missing what?

As it is dynamic ip and i don't know what ip's are available from the DHCP at given time, so i can't use static ip for it. (or do you mean i would look up what ip i get from DHCP and change it to that manually ?, is that possible?) (and i don't have admin access to DHCP server.)

in my win XP installation, i had:

1 network card:
Sharing my own network static ip and dynamic ip to workplace network, simultanously.

now that i bought that second nic, i have in win7:

2 network cards:
1st. NIC getting dynamic DHCP ip from my workplace, to access corporate network.
2nd. NIC for my own network. static ip.

If you are using a gateway device on your network:
Contact your it department and ask them for a static ip 9 out of ten times they are not going to have all ip's accounted for (planning for expansion)
If you dial in from your pc:
Your automatically assigned an ip address on your dial-in interface which acts as a virtual nic.

 

[sillik]

I could ask about static ip's, but as i now bought that another nic.. it is working fine.

but thx anyway.

Its doable. First open up your tcpip properties window and set it for Automatically Obtain. Once that is done click on the Alternate Configuration tab and setup your static IP address. Your PC will first try to obtain a Dynamic IP, if it can't get one after about 2 minuts it will switch to the static IP you set. I used only static IPs here at home and setup my daughters netbook this way. She complained about the 2 minute wait but it worked. Doing this let me keep my static IPs at home and her netbook would still work on other networks.

 

[sillik]

Actually not, what i'm looking for.. to use dynamic and static ip simultanously, one network card (2 networks) (win7)

OK, I missed the "at the same time" part.

I'm looking answer to this too, on winxp it worked with some registery hacking but now it doesnt seem to work...

Could there be an alternative with cloning the real nic into virtual one which connects to the LAN?

I want to bypass the modem bridge mode with this "hack" also its for some extra security...

Please don't start with the question "why you want to do that? why not use routed+nat?" and no, alternate configuration does not work.

Usually when you setup a network, you dedicate a portion of the address space to DHCP addresses and leave the remainder for devices that need to be static, like servers, printers, etc. So, 192.168.1.1 through 192.168.1.10 could be static, 192.168.1.11-192.168.1.200 could be dynamic and 192.168.1.200 to 192.168.1.254 could be static.

Extra security?
Giving yourself a Static ip is more secure?
When did this happen?

And yes you man make virtual Nics in vms. if your wanting to be more secure you would be using one

It's easier and more secure to manage LAN services if no one from the internet can reach them when the firewall is either on or off. (static ip for lan services + dhcp for internet)dns cache server, mailserver, fileserver and all that.

But yeah I'm back to routed mode, had too many problems with wlan+bridged mode. The modem I'm using has some hardware bugs that causes it to lose wlan connection, though now there is some performance issues >_>

Probably need to buy new modem...

I'm also looking for this answer. As you say, you could do it on WinXP (and I'm not sure you even needed a registry hack to do it either), but the functionality seems to have been removed from both Windows Vista & Windows 7.

Surely there must be some registry hack or something to get this working again?

The easiest solution is to use static Ip addresses. as you can set multiple gateways and Ips.
