Renumbering and DNS
When renumbering a site, the 64 rightmost bits do not change but the leftmost do
DNS Name-to-address mapping must be updated to reflect the new leftmost bits
A6 divide the Name-to-address query into subqueries
- Give me the rightmost 64 bits and the other entry that points to to leftmost 64 bits
- The entry for the leftmost 64 bits will be the only place in the DNS tree to change
