In this section you may find some details of additional operations for discovery/auto-registration events.
Hosts are added during the discovery process, as soon as a host is discovered, rather than at the end of the discovery process.
When adding a host, its name is decided by the standard gethostbyname function. If the host can be resolved, resolved name is used. If not, the IP address is used. Besides, if IPv6 address must be used for a host name, then all “:” (colons) are replaced by “_” (underscores), since colons are not allowed in host names.
