I do not know what exactly a DNS seed is, what exactly it is that I have to set up at the DNS-provider, in the zone-records of the domains I want to put DNS seeds into.
Once I have all those set up I can look into putting them into the code if our old caode even has DNS seed support in it.
(If it doesn't I can just find IP addresses to put into the last resort IP addresses list that is in the code.)
