Many of these organizations were allocated Class B networks anyway. Consequently, Class B networks quickly became scarce. To help solve this problem and create networks that were just the right size for all sorts of organizations, Classless Inter-Domain Routing, or CIDR (pronounced "cider"), was developed. As the name implies, CIDR does away with the old Class A, Class B, and Class C network designations. Instead of allocating either one, two, or three octets to the network identifier, the allocator could assign any number of contiguous bits of the IP address to the network identifier.
Au name server for the address and gets the answer. 2 Recursion You may have noticed a big difference in the amount of work done by the name servers in the previous example. Four of the name servers simply returned the best answer they already had—mostly referrals to other name servers—to the queries they received. They didn't have to send their own queries to find the data requested. But one name server—the one queried by the resolver—had to follow successive referrals until it received an answer.
1 Time to Live Name servers can't cache data forever, of course. If they did, changes to that data on the authoritative name servers would never reach the rest of the network; remote name servers would just continue to use cached data. Consequently, the administrator of the zone that contains the data decides on a time to live (TTL) for the data. The time to live is the amount of time that any name server is allowed to cache the data. After the time to live expires, the name server must discard the cached data and get new data from the authoritative name servers.
