I agree with the other commenters. According to the spec you should always get he same IP because your client will request the same IP as it has. As long as you haven’t changed networks or your DHCP lease hasn’t expired AND the server has already given it to another client, your IP shouldn’t change. Also, as long as you stay on the same wifi network ou should keep he same IP as the client will continually renew its DHCP itself when it’s lease time is half way up.

I agree with Paul. Most DHCP servers provide “pseudo-static” addressing. You’re likely to get the same address. The server will probably even “tombstone” your address for a period so you can have the same one back.

Most all DHCP implementations will hand out the same IP address every time you renew the lease (and a lot of clients will actually go so far as to request the same IP address) to minimize the churn in what is typically a busy, full pool

My mac and ipad and iPhone ere constantly conflicting with their ip addresses, but I didn’t get the message telling me this. Finally I discovered it myself, after months of waiting and intrigue. Instead of doing this everytime I just increased the range of ip addresses in my server. Though, if you were on a public network and couldn’t change their ip settings, this is a great troubleshoot. However, apple always says dont do this, just go to general, reset, network settings, reset : does the same job and if it is a different problem then it troubleshoots that, this only works with ip addresses.
