purpose of the RIR(for example RIPE) "domain:" object

[Martin T]

Hi,

what is the purpose of RIPE database "domain:" objects? Are they
practically used for something? And according to RIPE database manual,
"nserver" attribute under domain object specifies nameservers of the
domain- has this some sort of practical use or is it just informative
field(it's not mandatory according to "whois -h whois.ripe.net -t
domain")?


regards,
martin
