displaying some (undefined?) asn entries

[yvs2014]

Hello,

it's related to displaying some whois db entries, like

% whois -h riswhois.ripe.net 8.8.8.8 | tail
route:        8.8.8.8/32
origin:       AS4205777777
descr:         
lastupd-frst: 2023-11-17 17:22Z  91.206.53.35@rrc20
lastupd-last: 2023-11-17 17:22Z  91.206.53.35@rrc20
seen-at:      rrc20
num-rispeers: 1
source:       RISWHOIS

Is it possible to display the origin (from not-in-table prefixes) as an empty field? or in some a bit more descriptive way if that's an actual entry
