Any comprehensive listing of where Google's IPs originate from?

Hello,

We are trying to reduce latency to a region in Google Cloud which we are in the same city of. Latency is currently about 22ms rt for the traffic to go 9 miles.

I am having the hardest time finding any comprehensive list of what exchanges, transit, etc their IP addresses are being announced over.

Specifically trying to get closer to addresses in these prefixes:

34.162.192.0/18
34.162.64.0/18

Any info is greatly appreciated.

Thanks,
-Drew

note an entirely helpful answer, but google does publish:
https://www.gstatic.com/ipranges/cloud.json - where isp live in
'google cloud' (mostly where they live)
https://www.gstatic.com/ipranges/goog.json - prefixes announced

maybe 'where' was not 'location' but 'origination by as15169 and it's
client networks' though?

From my observations, all us-east-5 IPs are announced via transit and
peering at all of my locations Chicago and east.

i would expect that google announces the /16 at least from 'everywhere', yes.

100% chance the best option is peeringdb ....(I'm betting closest to
drew is chicago-land-ix-ville)

I see the specific /18s Drew asked about initially. Didn't check for the
covering /16.
