Someone told me once upon a time that seeds are not nodes but, rather, hostnames / subdomains / domains whose DNS is on a modified DNS-server, one that has been modified to use the list of current live nodes to populate the hostname with currently live nodes.
So basically instead of merely plugging into your DNS a whole bunch of IP addresses that people have claimed they would maintain nodes at, your DNS server itself answers DNS queries with the IP address of nodes that actually are alive at the time and actually do have their incoming port open at the time.

That's a pretty slick little trick.
Does anyone know of a repo for anything like that?
But wouldn't it just be a lot easier to have a simple HTTP response with a text list of 1 IP per line?
Is there any real advantage to using a modified DNS server?
