What do you think recommended values are ? I know have for everything in
193.in-addr.arpa:

@               IN      SOA     ns.ripe.net.      hostmaster.ripe.net.
                        (
                                   1.20  ; Serial
                                 14400  ; Refresh 4 hours
                                  3600  ; Retry   1 hours
                                604800  ; Expire  7 days
                                518400  ; TTL     6 days
                        )

which in my view is reasonable, since these things (just delegations) do not
change too often. For the actual class C zones, we have for
45.87.192.in-addr.arpa (RIPE NCC net):

@               IN      SOA     ns.ripe.net.      hostmaster.ripe.net.
                        (
                                   1.4  ; Serial
                                 28800  ; Refresh 8 hours
                                  7200  ; Retry   2 hours
                                604800  ; Expire  7 days
                                 86400  ; Minimum 1 day
                        )

Are these fine to be recommended ?
