I have been curious about IP addresses for a while. And I have a few questions.
I understand subnetting and the basics of routing but they are a few gaps in my practical knowledge.
[IPv4]
How does a hosting provider get an IPv4 address? [I know IPv4 is exhausted but I think there me some kind of after market for IPv4]
Can an individual get an IPv4 address or only a company/organization?
Can you sell IPv4 addresses?
How much does it cost to get an IPv4 address, is this a one off fee or is this yearly/monthly?
[IPv6]
How does a hosting provider get an IPv6 address?
Can an individual get an IPv6 address or only a company/organization?
Can you sell IPv6 addresses?
How much does it cost to get an IPv6 address, is this a one off fee or is this yearly/monthly?
[Both IPv4 and IPv6]
How is an IP address associated with a physical machine on the public internet.
Can you buy your own IP address and tell your hosting provider I want to use this address instead of the ones they give you? Is this difficult, what would be involved?
May have some follow up questions based on your responses.
Thanks in advance.
