Rachel Casali commented: This is an issue Comcast faces today. What is a "Reasonable" number of IPs?

From Knz: To this and the other remark below about how AWS EC2 "chews up IPs unreasonably" I would suggest that Managed CockroachDB use IPv6 intra-cluster and below load balancer, and only issue IPv4 addresses to the load balancers (for clients).
