The seeder supports subdomaining by a whitelist filter according to node service flags.
This patch adds NODE_NETWORK_LIMITED to that whitelist by default.

Backport of this commit: https://github.com/sipa/bitcoin-seeder/commit/002bc0bbd5bfd721d7c80d7cdd35a47165f7c1ff

Run the seeder until it has hundreds or thousands of nodes crawled:

./src/seeder/bitcoin-seeder -host=seeder.status.cash -ns=localhost -mbox=thonkle@protonmail.com -port=5555

Each subdomain should return results according to the filter:
NODE_NETWORK:
