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?
You're likely to get different answers to this, but the 'magic number' appears to be /48. Looking in the v6 BGP table, you will likely find smaller prefixes than that, but a number of the major carriers seem to be settling on /48 as the smallest prefix they will accept. /48 is also the smallest block most of the RIRs will assign to end-users.
