I've always been under the impression its best practice to only announce
prefixes of a /24 and above when it comes to IPv4 and BGP.
I was wondering if something similar had been agreed upon regarding IPv6.
And if That's the case, What's the magic number? /32? /48? /64?
At this point, you can depend on being able to announce a /32 from any
block and a /48 from an RIR block designated for end-user assignments.
Many carriers have more permissive policies but all of any consequence
now allow at least that.
