134.63.89.179 is owned by an ISP called Tektronix in Beaverton, Oregon. This seems to match an entry on the current EmergingThreats black list: 134.62.0.0/15 (as of Jan 27, 2017) That mask covers from 134.62.0.0 to 134.63.255.255, so it's possible that the blacklist is over-broad. (Or maybe the Earth Defense Alliance is blacklisted [Bonus points for getting the reference])
107.113.28.33 is owned by AT&T Wireless in "United States." I don't see that range on the blacklist.
It's hard to say without more information, but it appears that you have an AT&T customer on your wi-fi hitting a potentially bad IP.
