Hostnames non validi

salve, ho bisogno di aiuto se possibile, da un po di tempo ricevo dei floods da questi hostname:

Wimax-Cali-190-70-156-
host57-125-dynamic.22-
pooldmz.presidencia.g
Arennes-352-1-119-221
201-11-236-157.smace70
host47.201-252-62.tele
tpnet-to-u3d.u3d.net
bix232.neoplus.adsl.t

Sono riuscito a bloccare tramite iptables tutti gli indirizzi ips eccetto gli hostname quì sopra perchè non so come fare a bloccarli, non conosco l'indirizzo ip e se faccio un ping mi salta fuori che non sono hostname validi.
Come faccio per sapere a quali indirizzi ip equivalgono?
e come posso bloccarli tramite iptables dato che non sono hostname validi?

[funcool]

Non riesci a trovare gli indirizzi IP perché tutti quegli hostname, tranne uno ("tpnet-to-u3d.u3d.net" => 83.3.27.90), non sono completi.

Salve, per fortuna che uso la funzione cerca

Ho avuto lo stesso problema di nontrovatoit.

Gli hostname non sono validi

Ecco uno screenshots se non ci credi:

perchè non risco a risalire agli indirizzi ips di quei hostnames? ogni volta mi dice hostnames non validi.

PS ho censurato con ***** la parte che riguarda il mio server.
