Current address on my home network is 192.168.1.84.  How to make certain this address does not change (to allow for consistent communication with my iPhone)?

Two main ways:

1) If your router supports static assignments, you can tell it to always assign that IP (usually based on MAC ID of the device)...

2) If the router doesn't support static assignment, you can fix the address manually in the TCP/IP properties of the adapter... BUT... to prevent duplicate assignment of the same IP address elsewhere by the router, it should be a fixed address OUTSIDE the DHCP range of the router!

Check here:

for a visual reference on the 2nd method...  The first depends on your individual router.

It's relatively easy.  This tutorial can help guide you through the process...

You will need to open a command prompt and retrieve the current ip address information for subnet (probably 255.255.255.0) and default gateway ( possibly 192.168.1.1)

Your 192.168.1.x addresses are not routable over the Internet, so this configuration will only work when connected to your home wifi.

Most dhcp servers will check for conflicts before assigning an address.  Look in your router documentation for the specifics on reserving an IP address.

Right click on the network symbol in the system tray. Open network and sharing center. Change adapter settings, right click on the adpater you want to change

What router do you have?
Then we might be able to tell if it supports "DHCP reservations" or not.

It's a new Netgear Model B90-755025-15 supplied by AT&T last week when my old router failed. They wanted to sell me an expensive Connectic service to make it work.  My other option is to return it and get a compatible router that does the job.
