Sounds like a lease being renewed. For a more educated guess, like Andrei said, it would be good to know which network manager you're using. If a lease is being renewed, you _might_ also find indications in the log.
This is from my TW system "office24" :

This doesn't actually cause /run/netconfig/resolv.conf to be updated, but maybe it does on yours.
