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. -- Regards Bill; Fedora 9, Gnome 2.22.3 Evo.2.22.3.1, Emacs 22.2.1 -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
