Does maradns support star (wildcard) records?
Yes. MaraDNS supports both having stars at the beginning of records and the end of records. For example, to have anything.example.com. have the IP 10.1.2.3, add this line to the zone file for example.com: *.example.com. A 10.1.2.3 To have stars at the end of records, csv2_default_zonefile has to be set. The mararc parameter bind_star_handling affects how star records are handled. More information is in the mararc man page.
