Some IP lookups tell me that an IP like 35.247.9.x belongs to AS15169(35.244.0.0/14) which is Google (googleusercontent). Other information I get say that 35.247.9.x is in Ann Arbor and belongs to Merit Network.(which if I recall, Merit was operated by U-Mich). I'm guessing that 35.244.0.0/14 does belong to Google, but puzzled why the linkage to Merit / Ann Arbor?
