A good solution to switch between different network settings?

Here are two programs to switch between pre-configured network settings:

IP Organizer 2

The website is in Turkish. Here's the download link.

IP Organizer is freeware.

NetSetMan

NetSetMan is free for personal use.

If your solely problem is switching between DHCP-enabled and static IP networks on Windows, then you don't need any extra software at all. Since ye olde Windows XP days you can switch between "normal" and "alternate" configs for your network connections. Go to your Network and Sharing Center, find your connection (it may be the active one), click on it (or double click if you had to go to Change Adapter Settings), click on Properties, Internet Protocol Version 4 or 6 (TCP/IPv4 or v6).

Then in the dialog you'll see the usual network configuration and a tab for an "Alternative Configuration". You can set up one for your automatic configuration via DHCP and another one for a static IP configuration. When there's no DHCP server, Windows will use the other one.
