If for some crazy reason you wanted to give each byte of memory and storage in a supercomputer its own IPv6 address, you'd be able to scale up to 300 septillion (301,936,594,947,653,725,323,264) nodes, each with 1 terabyte of RAM and 1 petabyte of storage, before IPv6 ran out of individual addresses. That's not even counting the 65535 ports you could then use.
