It could be NetworkManager's connectivity detection.
Check /etc/NetworkManager/NetworkManager.conf and see if there is a
[connectivity] section, and also look in /etc/NetworkManager/conf.d/ to
see if there is a snippet there for connectivity too.  Your distro
(Fedora 21 perhaps?) might have enabled connectivity checking by
default.

NetworkManager's connectivity detection periodically contacts a
user-configurable HTTP address to check whether you have network
connectivity or not.  GNOME and other clients use this to show WiFi
hotspot logins and indicate network state.  But it can be turned off
quite easily.
