Keep static IP for each network?

[cclloyd9785]

Is there a way I can keep a different static IP for each network I connect to?

Like on my house, I wanted 192.168.1.200 (Which worked till I connected to a different internet)
And at my friends house, when it connects, it connects with 192.168.1.150.

and as I reconnect to whichever internet, it switches to that IP.

Yes, and it's quite easy to do. Routers and modems we normal users use to connect to Internet normally use IP addresses in series 10.0.X.X, 172.16.X.X or 192.168.X.X. So, for instance your router's IP i.e. your DHCP server address is most probably 192.168.1.1. If you now let's say visited me, you could not join my network keeping your old IP because my DHCP server address is 192.168.2.1

If you didn't have a static IP to connect to my router, it (DHCP server) would then assign you an IP address from my address pool, which I have limited to 99 addresses as this image shows:



If you visited me often, we could for instance agree that you can always use 192.168.2.15 when here. You can set a static IP for every network you normally use as for instance I have set this laptop to have these two addresses (WiFi & LAN) when home here in Leipzig:



When in our other home, other side of Germany, I have two other static IP's. I also have a static IP to use in my favourite pub; the owner is a friend and let's me use his fast gigabit office network so I don't have to use the slow public WLAN when sitting there with my laptop.

To create a connection for every network you regularly visit, open the Network and Sharing Center, click Connect to a network, and follow the instructions.



Go then to each connection's properties and set DHCP, DNS and IP info manually. Result is this:

As Kari said, as long as the router you are connecting to is in the same subnet...

In a private use Class C IP address like the ones you describe are at home and your friends house. 192.168.1.0 is the subnet ID, and most home based routers use either 192.168.1.1 or 192.168.1.254 as their default IP's, and 192.168.1.255 is the broadcast ID for all of the IPs in that subnet. You should be fine setting your static IP on the lappy to say something in the range of 192.168.1.110-120. And connect to most networks fine as that is the most common out there!

If however one of the networks you wish to connect to with that NIC (network adapter) is anthing other than a 192.168.1.??? network you wont connect until you change the card back to a dynamic IP served up by the router or a static IP in that address range... 10.0.0.0 (class A private space)or a 172.16.x.x (class b private space) are typical other ranges used.

Hope that helps explain!

Just finished editing my previous post. This time I really noticed what can happen, how wrong info you can give, when reading the question wrong.

OK, my excuse is whisky Anyway, I first read the question to be if it would be possible always, everywhere use the same static IP. Posted a reply, and then noticed that I had the question completely wrong.

This rant is meant to be a public apology; if someone read my first reply, he / she could have got completely wrong idea.

Sorry. No more whisky tonight. Maybe one or two but no more...

Not trying to steal the op's thread but it's relevant but is it possible to do something similar by creating a .bat file eg. "friends connection" which contains

netsh interface ip set address name="Wireless Connection" source=static addr=192.168.0.10 mask=255.255.255.0
netsh interface ip set address name="Wireless Connection" gateway=192.168.0.1 gwmetric=0
netsh interface ip set dns name="Wireless Connection" source=static addr=192.168.0.1

And another .bat file eg. "Home connection" which contains

netsh interface ip set address name="Wireless Connection" source=static addr=192.168.1.10 mask=255.255.255.0
netsh interface ip set address name="Wireless Connection" gateway=192.168.1.1 gwmetric=0
netsh interface ip set dns name="Wireless Connection" source=static addr=192.168.1.1

I haven't played with this but in theory it should work ?

His and his friends are on the same subnet... 192.168.1.x... a static IP in that space will work for both networks! Just set it to anything in between .2 and .253 and it should never need to be changed for most private routers.

Hiya Darryl

Thanks for the reply, but like I said I didn't want to steal the op's thread, I was just wanting to know that if the 2 locations were on a different subnet would a bat file like I showed work.

soz for the confussion

 

[Kari]

Me too, I am sorry.

I tried to cover every possible DHCP and subnet, thus telling how to do it for every network which he visits separately. Of course if if it's only question of home and one other place and the subnet is the same, then it's enough to have just one static address.

I repeat my excuse: CEO of our household gave permission to leave the pills for one night and have some whisky...

Darryl, don't tell other geeks here but it's not the first time...

Seriously, once or twice I have waked up with a really bad case of hangover, read what I'd posted the night before and then deleted almost everything from past 24 hours. Happens...

Yes, it should work!

And to the OP... a static will work as long as both your and friends routers use the same IP address because you will have to put that IP (routers) in as the Gateway and DNS server if you go static. And any other private networks that use the same IP for their router!

Personally, I love Win7 and it's location aware network settings.
Control panel-->Network and Internet-->Manage Wireless Networks--> Add.

I simply add a network into my laptop utilizing that networks SSID, encryption type, passphrase, etc. Then anytime Im in range of that network I connect and have access to its Internet, printers, shares, etc. All the WEP, WPA, and WPA2 encryption is remembered and I dont have to do anything but fire up the laptop and Im connected! Makes life a breeze when moving from network to network!

The best and easiest way to do this is to list the different connections "Ip's, DNS, subnet, gateways" in your advanced TCP/ip properties window. You can even list more than one subnet there. Using this window keeps you from having to designate new settings for each connection. You can just list them one after the other.

Simple, elegant and easy. A good tip.

TLDL all posts. (Also dont want to use any other software)

I sorta see what you guys are saying, but the main reason I want this is even though we both had 192.168.1.1 as the subnet mask, 192.168.1.200 didnt work on my friends internet (it said DCHP or something wasnt enabled) and 192.168.1.150 doesnt work on my internet (Because its already in use by my xbox.)

It connects to the router, but I dont get internet.


And another thing, I cant find that page that chev65 posted. Is it possible because I use wireless or something?

The page is there but I didn't post the exact pathway, wireless or wired it works for both.

In the first window right click the IPv4 line and choose properties, then click the setting to "use the following IP address" this will allow you to choose a static IP in the advanced TCP/IP properties. You can do the same for the DNS server although it usually works best to let the router do that part for you.

After that choose the "Advanced" setting which gets you to the TCP/ip settings window. You then choose the "Add" button to add info from the network you need to set up.

Click add again to set up the next network, you can list the networks one after the other.

It works really well and will retain your static IP's and other settings from each network.

 

[cclloyd9785]

Yea but it doesnt let me do that for individule networks. It only lets me do it for my wireless adapter for all networks at once.

 

[WindowsStar]

Do you not want to use a Command Script?

If you do you can us poolman's post: http://www.sevenforums.com/network-sharing/127063-keep-static-ip-each-network.html#post1097340

If not you could most likely use a VBS script to flip it back and forth or set it to something you want.

 

[chev65]

Yea but it doesnt let me do that for individule networks. It only lets me do it for my wireless adapter for all networks at once.

I can assure you that it works absolutely perfectly.

If you clicked on the wireless adaptor first then thats the one you will be adding static IP's for. If you need to add extra static IP's for your wired eithernet adaptor then click on the IPv4 properties of your wired connection adaptor. You can add more than one static IP for each adaptor as required.

You need to use the "Add" button after entering the info for each network. The Add button allows you to enter next static IP.

To make this perfectly clear I have set up two different default gateways and IP's as an example. You would only need to enter the second default gateway if the default gateway on the other router is differerent than the first one.

I can't think of any other way to explain this better. Hope this helps you out cclloyd.

Sorry but I forgot to add another file that goes along with my last post. If you want to resort back to a "dhcp" setting then you need to create a .bat file eg. (my dhcp) which contains the lines

netsh interface ip set address name="wireless Connection" dhcp
netsh interface ip set dns name="Wireless Connection" dhcp

* please note

"wireless connection" is only used for the wlan if you want to create .bat files for the wired connection then substitute the "wireless connection" (or what ever yours is called) with "Local Area Connection" (or what ever yours is called)
