CKN23-ARIN

It's at least somewhat inherent to the technology. DOCSIS download channels are shared among subscribers; upload channels are allocated exclusively per-subscriber. This architecture provides economic incentives for the provider to provision asymmetric circuits rather than symmetric ones.

It's asymmetric, providing far less upload capacity than download.

The letter specifically calls for symmetrical speeds of at least 100Mbps. Let's hope that this is the death of PON-based FTTH.

Jealous! I pay ARIN hundreds of dollars a year in RSA fees.

As a legacy address holder, how do you feel about RPKI?

I think we'll still see some people doing NAT66, unfortunately.

The exception to this is a handful of remaining "legacy" pre-RIR address holders. I'm surprised AWS, etc. are so willingly handing the addresses they buy from legacy holders over to ARIN.

What kind of entities does your broker rent them out to? Are you worried at all about tenants trashing your IPs' reputation and future market value?

The smallest routable IPv4 network on the Internet is a /24, which is 256 addresses. Regional Internet Registries won't assign you smaller than a /24, but individual ISPs might. Even if you have an assignment, maintaining it requires payment of annual fees to your RIR, unless you're a lucky "legacy" address holder from before the RIRs were formed.
