Answer 1

Check you router make sure is set to DHCP instead of statics or try doing ipconfig /flushdns then ipconfig /release and ipconfig /renew

Answer 2

You won't see anything. Technically, you were always dynamic. the DHCP server of your ISP put your MAC address in with a specific IP address. When your system got an address, it always got the same IP address. To change it, all they did was delete the entry.



Now to really be dynamic, you need to make sure your equipment is set to pull a dynamic address. If it isn't, you may suddenly lose connectivity one day when your ISP offers your address to someone else.



if you do a "IPCONFIG /ALL" on your system, it should list the DHCP server. If it says static, you are not set up correctly. change the settings to Obtain an IP address automatically, and Obtain a DNS server address automatically.

Answer 3

Maybe a dumb question, but why do you care? If it's dynamic now, great. It works. So whats the point?

Answer 4

you misunderstand. it will always show static during any given session. what a dynamic IP address does is assign the IP address when you connect to the first router in the ISP's system. On the next connection, you get the first available IP address, which may not be the same as the prior session [and usually isn't]. Static IP address always provide the same IP address to your connection [and thus are a lot simpler to address from the other end, like if you're running a small scale server for something.]

Answer 5

Your old static address was probably changed to dynamic, but has not reached some timeout (reset) period used by the ISP. So, you keep the current IP until the ISP's lease time or pool reset happens.

Answer 6

No need to wait.
