DHCP-Client spam in eventlog

Hello I was just looking in my eventlog and I noticed that each 15th second I
am sucessfully assigned a new IP address which I have no clue on why?

This is the message I get:
[General]
Your computer was successfully assigned an address from the network, and it
can now connect to other computers.

I guess my question is, why do my eventlog get spammed with this when all my
NICs already have an IP assigned?
