I am using Bind 8.3.4.
Is there a way to delegate of all 3rd level domains to a name
server without creating NS entries for all the 100 3rd level domains
like below :
In the zone file of db.def.com
domain1 IN NS svr1.def.com
domain2 IN NS svr2.def.com
domain3 IN NS svr3.def.com
domain100 IN NS svr3.def.com
Can I use wild card to save entering all the 100 domain describe above
