[arin-discuss] Facebook /20, Google /16

[Alex Ryu]

They may have a lot of distributed systems to require their own unique IP addresses. 
Also, redundant geographic locations for disaster recovery? 
Do not assume that their service will be served by single or a few hosts. 

I believe ARIN hostmaters are doing due diligence to check efficient usage of their IP address for justification.

Anyone have any idea why Facebook would have a full /20 assigned to them?
Seems to me a fine example of the waste that we have out there with IP's.  

Google is another - they own a /16.  Ugh!!

Yeah, I know, we all complain about it, but come on!  That just doesn't make
sense.
