Hi;
My question is quite narrow. I am not looking for generalized
explanations of IPv4.
When ARIN (American Registry for Internet Numbers or one of its clients,
or any other IANA RIR) assigns a /8, or /16 number and registers a new
domain name is there any rules, policy or usual practice in the
assignment that gives a hint to the nature of the entity that has
received a certain address?
E.g. If I see 64.71.255.198, could I reasonably say "That's a name
server, or, that's a Rogers Cable Inc. address" or glean any other
information about the organization, company or purpose? Or are all such
address assignments simply arbitrary? If there is such a rule, policy
or usual practice, do you know where I could find it and/or see a table
of such assignments.
I have done my google due diligence. Every site, official and
otherwise, remains silent on the question. That usually portends a
negative; there is no such policy -- but ya' never know.
Use "whois" to glean information...
