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.)

You control the zone - so assuming you use a secure approach to management - then lookups will be under your control and done in a responsible way.
I think the terminology has been confused a bit. The nodes, from what I understand are just full time nodes running on a server with a fast connect and configured to allow a high number of connections to help bootstrap other nodes - ala seed nodes.
You can use DNS round-robin to make config easier for people. They can just point to a single name - and DNS is setup to round-robin or to use an algo to distribute traffic over the set of DNS records - distributing the traffic a bit.
As IPV6 isn't enabled in dvc (from what saw after a quick lookup) you can't use anything smart with srv records.
With geoDNS for ipv6 or normal IP - you can config things a little smarter as many of the geoIP setups allow you to group a set of DNS records per geo zone.
This would allow EU users to lookup a DNS entry - and get back a subset of the records - so they have a faster bootstrap time than connecting all over the globe when bootstrapping the blockchain.
