🗒️ Summary of this message: A possible bootstrap method for Bitcoin involves using a convention of bitcoind listening on a specific last octet of IPv4 address, .14 when possible. If no other method works, the client could start scanning x.x.x.14 addresses.
📝 Original message:one possible bootstrap method of last resort,
1. create a convention of bitcoind listening on a specific last octest
of IPv4 address, let's say, .14 when possible. Those of us who have
access to IP space would use .14's.
2. if no other bootstrap method works, client could start scanning
x.x.x.14 addresses, perhaps in some semi-intelligent order (starting
from more pobable /8's and /16's), if enough people place bitcoind on
x.x.x.14 than after a 10-100 thousand checks it bound to find a
bitcoind peer.
It's messy, with all the excessive scanning etc... but it does not
depend on anything except a bunch of bitcoind by convention preferring
listening on x.x.x.14's.
Given that this is a method of last resort in bootrap chain it whould
hopefully not lead to DDOS on those unlucky to own *.14 and not
running bitcoind there. Also the more people are running bitcoind on
.14, the quicker it would find a peer, the less scanning to do. It is
kind of self-regualting.
For whatever it worth...
