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 ?

I think the following could be reasonable values and rules to recommended. Refresh and retry have a direct impact on how much ns.ripe.net will have to do when acting as secondary for delegated 256-Cblocks. Maybe Piet Berteema has something more to say on this subject. ( yymmddv ; Serial 28800 ; Refresh 8 hours 3600 ; Retry 1 hour 604800 ; Expire 7 days 172800 ; Default TTL 2 days ) where yyddmmv is the recommended way to hold the update serial number with yy being the two-digit year number (to become four-digits on year 2000) mm being the two-digit month number dd being the two-digit day number v being a one digit serial number ---------- ---------- Antonio_Blasco Bonito E-Mail: bonito@nis.garr.it GARR - Network Information Service c=it;a=garr;p=garr;o=nis;s=bonito c/o CNUCE - Istituto del CNR Tel: +39 (50) 593246 Via S.
