I often create a wireless ad-hoc network on my laptop running Windows 7. Now I'd like to connect to it using standard HTTP from my iPod Touch. I've tried 192.168.1.1 and that doesn't work. What should the address be so I can connect?

  • Is your iPod on the ad hoc network? – ceejayoz Feb 15 '10 at 17:21

It could be that Windows is using APIPA, so you could try an IP in the range of 169.254.0.1 to 169.254.255.254 (169.254.0.0/16). That tends to be what (from my experience) Windows uses in ad-hoc networks.

  • This is the closest anyone's got to a useful answer. The iPod touch is assigned an IP of something like 169.254.x.x every time... Running ipconfig on the host computer leaves a blank field for IP address, almost as if it's "hidden". – Redandwhite Feb 17 '10 at 0:32
  • RedandWhite - In windows when a device is given a 169.254... address it usually means that there is a problem with the DHCP and the device is unable to pick up an IP address. This may not ring tru on an Apple though - just my tuppence. – Joe Taylor Feb 18 '10 at 16:30
  • In reality, it doesn't mean that there is a "problem" with DHCP; it just means that it was unable to get an IP through DHCP and automatically assigns itself an IP in the 169.254.0.0/16 range. It's APIPA (Automatic Private IP Addressing) and it IS a standard that is supported, even on the iPod Touch/iPhone (and really, on most any networked device). – squircle Feb 18 '10 at 23:14

The easiest thing you can do is go to the command prompt and type ipconfig.

Now, take a look at both your wireless's IP and subnet mask. You should see a section similar to this:

 Wireless LAN adapter Wireless Network Connection:

   Connection-specific DNS Suffix  . :
   IPv4 Address. . . . . . . . . . . : 192.168.0.9
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.0.1

You want to take a look at the line IPv4 Address. In this example, the host is 192.168.0.9

  • running "ipconfig" on an iPod Touch? interesting ... – Molly7244 Feb 15 '10 at 18:21
  • @Molly I thought he asked what the host's ip is e.g. the Windows 7 machine? – William Hilsum Feb 15 '10 at 18:52
  • but then he wouldn't see a default gateway, as the host IS the gateway in an ad-hoc network and the IPv4 address would be .1 – Molly7244 Feb 15 '10 at 18:54

    @Molly, but I thought He wasn't asking what the default gateway is, he was asking what the host's IP was, and I guess you thought the same as you gave the host IP as well, I just said how to find it rather than what it (may) be. – William Hilsum Feb 15 '10 at 19:02
  • quite so, but you wouldn't see a gateway on a controller setup as host for an ad-hoc network, IP (.1 by default) and subnet, that's it. – Molly7244 Feb 15 '10 at 22:53

If running out of options, try to look at the Address Resolution Protocol (ARP) cache: arp -a or arp -a -v for verbose mode.

Then match the MAC address with the interface you're after. You can get the list of MAC addresses on your machine with ipconfig /all.

First make sure that your iPod is connected to the adHoc network. Second, the machines on your ad-hoc network will assign themselves IP addresses after checking to make sure that the address is not already in use. Therefore the IP address maybe different every time your create/connect to the ad-hoc network. To find out how to view your current IP address check out this webpage: http://www.groovypost.com/howto/microsoft/windows-7/find-your-local-ip-address-windows-7-cmd/

The host IP address should be 192.168.0.1.

  • On an Ipod touch there are three sections: DHCP,BootIP, Static Now in each section, there are fields and the main ones are: IP Address: Subnet Mask: Router: DNS: You can manually change the Static, if you know the ip address of your computer and router. Then statically assign your Ipod touch to an IP address that is free. The Subnet mask on a 192 address will be 255.255.255.0 as it is a class C network. The Router will be the ip address of your router (we think, if it doesn't work then change it to the pc) if you're router acts as your DNS provider then enter this as your DNS, – Joe Taylor Feb 18 '10 at 16:36

The poster asked the question 'how to determine what IP address was created after he created a WiFi ad-hoc network'.

The answer is to run, from the command prompt, 'ipconfig'.

Here's my output from a real ad-hoc network I created on my Windows 10 PC (with USB WiFi dongle): image You'll notice there is no default gateway (this is normal for the ad-hoc network host).

To connect to it from another WiFi-enabled device, the ad-hoc SSID (network name) should appear in the network list. If you're using a smartphone (ie. Samsung Galaxy 4 in my case) then you'll just tap on the network name, enter the password, and you're connected. Similarly, from my Windows 7 laptop (with built-in WiFi), the ad-hoc network name will appear in the list of available networks - I just click on it, click on the 'connect' button, enter the password, and I'm connected. If you do an ipconfig from the 'client' (my Win7 laptop) you'll see something like this: image Notice how it has a default gateway and DNS entry? This is normal.

Knowing the IP address of the ad-hoc server is only useful if you want to programatically connect to it via a socket (ie. for client/server communications).

From what I've read Windows XP would create wifi ad-hoc networks in the 169.254.173.0 Class C range. For Windows 7 and 10 the network would be in the 192.168.137.0 Class C range. I've no idea if this can be changed.

Also, what would I do if I wanted a network with a Class B range? Why? Class C would only allow me to have a private wifi network with 254 devices connected. A Class B network would allow 65,000+ connected devices.

For those of you interested in creating a wifi ad-hoc network on Win7 or Win10 desktop OS, from the command prompt type: C:> netsh wlan set hostednetwork mode=allow ssid=myadhocnw key=12345678 C:> netsh wlan start hostednetwork Read up on the netsh DOS command to learn more.

Also people, don't get confused between a wifi ad-hoc network and a wifi hotspot (an ad-hoc derivative). The hotspot version allows you to share your internet gateway over a ad-hoc network. Wikipedia has some good articles for you to learn more.

I hope this post helps others progress further with their understanding and ad-hoc setup.
