Sper sa am timp sa "produc" un "google rank checker" cat de curand. Pana una alta, o lista cu majoritatea adreselor IP pentru datacentre-le google nu strica nimanui.

cred ca ajunge unul din fiecare clasa :/
Teoretic da. Practic, nu
Teoretic da. Practic, nu toate sunt accesibile 24/7. Daca e sa fac un update la lista de mai sus, acum (exact in momentul de fata) am peste 510 ip-uri accesibile. Maine pot fi mai putine sau mai multe. O singura adresa de IP reprezinta (asa cred eu) un singur set de date hostat intr-un "cluster". Rezultatele unui query nu se schimba atat timp cat IP-ul ramane alocat clusterului respectiv, sau nu se face upgrade la bazele de date din cluster.
Daca ne luam dupa ARIN, Google are urmatoarele clase:
Google Inc. GOOGLE (NET-216-239-32-0-1) 216.239.32.0 - 216.239.63.255
Google Inc. GOOGLE (NET-64-233-160-0-1) 64.233.160.0 - 64.233.191.255
Google Inc. GOOGLE (NET-66-249-64-0-1) 66.249.64.0 - 66.249.95.255
Google Inc. GOOGLE (NET-72-14-192-0-1) 72.14.192.0 - 72.14.255.255
Google Inc. GOOGLE (NET-209-85-128-0-1) 209.85.128.0 - 209.85.255.255
Desigur, RIPE, AFRNIC, APNIC vor raporta si ele IP-uri care se pot adauga listei pentru zonele respective.
Din nou, teoretic, poti afla prin ce tari sunt daca combini informatiile de la registrare cu o baza de date aflata la http://www.dplanet.ch/users/subspace/lastdump.zip
(schema IP-uri/tari este generata astazi Ianuarie 6).
Practic, exista 41 de blocuri clasa C si 41 de URL-uri de genul xxx-xx.google.com (unde xxx-xx poate fi unul din urmatoarele: gfe-au, gfe-ar, gfe-bf, gfe-bp, gfe-bu, gfe-bx, gfe-cw, gfe-dc, gfe-ed, gfe-eh, gfe-ff, gfe-fg, gfe-gv, gfe-he, gfe-hk, gfe-hs, gfe-hu, gfe-ik, gfe-in, gfe-jc, gfe-jp, gfe-kc, gfe-kr, gfe-lm, gfe-lo, gfe-mc, gfe-nf, gfe-nz, gfe-od, gfe-po, gfe-py, gfe-qb, gfe-rn, gfe-ro, gfe-tw, gfe-ug, gfe-ui, gfe-va, gfe-wr, gfe-wx, gfe-yo) care raspund la query-uri.
In plus, pentru multe din URL-urile de genul gfe-cw.google.com se pot adauga URL-uri extensie gfe-cw2.google.com si gfe-cw3.google.com
Mie imi place sa vad pe unde sunt si ce arie acopera, nu sa le folosesc pentru informatia care poate fi extrasa din ele. Asta e alt full-time job.
