The following examples illustrate the operations a resolver must perform for its client. We assume that the resolver is starting without a cache, as might be the case after system boot. We further assume that the system is not one of the hosts in the data and that the host is located somewhere on net 26, and that its safety belt (SBELT) data structure has the following information:
Match count = -1 SRI-NIC.ARPA. 18.104.22.168 10.0.0.51 A.ISI.EDU. 22.214.171.124
This information specifies servers to try, their addresses, and a match count of -1, which says that the servers aren't very close to the target. Note that the -1 isn't supposed to be an accurate closeness measure, just a value so that later stages of the algorithm will work.
The following examples illustrate the use of a cache, so each example assumes that previous requests have completed.
