Find Network Info


When setting up a BlueSCSI Wireless connection you’ll need to know the IP details of your network. This page will help you find them.

What you’ll need to find

At minimum you’ll need the following:

  • Subnet
  • Router IP aka Gateway IP
  • DNS
  • A free IP to use (when not using DHCP)

iPhone

If your iPhone is connected to the same network as you wish to connect your BlueSCSI you can find the information.

Goto Settings -> Wi-Fi under “My Networks” click on the blue I next to your Wi-Fi name for Info.
Scroll down to “IPV4 ADDRESS” section.

Here you will see an IP Address, Subnet, and Router. Make note of these.
To find your DNS click “Configure DNS” and note the first DNS Server. Note this address. Any IPV4 addresses will work. If it has a : in it it is an IPV6 address and will not work.

macOS

Open Terminal.app, run the command: networksetup -getinfo Wi-Fi
eg:

$ networksetup -getinfo Wi-Fi
DHCP Configuration
IP address: 192.168.1.27
Subnet mask: 255.255.255.0
Router: 192.168.1.1
...

Lastly get the DNS server by running:

ipconfig getoption en0 domain_name_server

eg:

$ ipconfig getoption en0 domain_name_server
192.168.1.150

Windows

Start->Run->cmd

Run:
ifconfig /all

Finding a free static IP on your network

After you’ve found your IP - lets say it is 192.168.1.27. Use the ping command on your computer to find another one that does not respond. This is the one we’ll use.

Open the terminal
- Windows: Start->Run->cmd
- macOS: Terminal.app

Run the command ping 192.168.1.28 (note we incremented the last number.

If you see a failure such as a timeout or unreachable this is an IP you can use for your vintage Mac.

$ ping 192.168.1.28
PING 192.168.1.28 (192.168.1.28): 56 data bytes
Request timeout for icmp_seq 0
