Yes, netname is not unique, multiple prefixes can be (and are)
named by the same. Thanks for commands, but the result is the
same -- i need to ask the right server:

    whois -h whois.apnic.net -T inetnum "chinanet-js" | grep inetnum | wc -l
    23

    whois -T inetnum "chinanet-js" | grep inetnum | wc -l                       
                         
    0

Of course, from "chinanet" one can guess APNIC, but still guess
only, and other names can be less obvious...

I check two rdap's client docs (mentioned nicinfo and python's
ipwhois), no one mentions netname (or so) in its query description
nor in examples, thus i don't expect to get useful info from it.

regards
