Network Challenge #6 Not enough IPv4 for my Data Center

/24 for every rack – Genius!
▪ Math is easy
▪ Subnet mask is easy to remember
▪ Wastes a lot of space
▪ 254 usable addresses
▪ 80 addresses in a rack
▪ /25 is what we could re-number into
▪ Not enough savings
▪ Do it if you want to get to IPv6 faster
Solutions
▪ re-number/re-subnet IPv4
▪ Too much code assumed racks are /24
▪ Too much code assumed clusters are /n (where n < 24)
▪ /25 doesn’t save us much
▪ IPv6
▪ Easier to overlay IPv6 on top of the network than re-subnet
▪ Can be done without taking datacenters/clusters offline
▪ Most importantly, you can test incrementally and iterate

Quotes on Motivation for IPv6 (Paul Saab, Paris IPv6 World Congress) Scale: • “Ran out of RFC 1918” Simplicity: • “Much easier to handle
two stacks at the edge, one internally”
Service: • “ip:port no longer a
reasonable way to identify a service”
• “Engineers asking if they can start writing IPv6-only code”

• IPv6 Routing. No NAT. • No VLANs Needed • Isolation via filtering on IPv6 address or
via extension headers • Dual stack tenants via MAP
