If we actually reached a host, it is recorded in the database as a target to be used in future scans.

label=value (or) label=date:valueThe date is yyyymmdd, not Y10K-ready. The labels may be:
Path a comma separated sequence of IP numbers, possibly followed by a completion code and a list of round-trip times in milliseconds Probe when this path was last checked Target a host on the destination network, if found Whiner date and email address if they don't want to be scanned Asnpath not used Name name of the network. Not implemented yet. Complete path scan completion code. deprecated. Pathdate path date. deprecated.There may be multiple paths for different dates in early versions of the Internet mapping data. If other fields are duplicated, only the newest is kept.

These may be followed by a semicolon and a comma-seperated list of round-trip times in milliseconds. Note: these are not necessarily monotonic: times include routing variations and dead-packet processing times, which appear to be slow-pathed in most routers.

The label may be the name, the site that said it doesn't exist (if in parens), or simply the IP address if no response was obtained. The label represents the first PTR record returned.
