Re: Help requested for zone delegation using DLZ

I garbaged up the earlier email.  Cut and paste occasionally can blow up...

I finally solved this tricky little problem with no code modification on
bind 9.5 and up (it should work for earlier versions but I do not have any
instances deployed anywhere).  To get this to work you need to perform the
following:

On Server A:

Create an NS record for us.example.com and an A record for the nameserver in
the parent (example.com) domain you will be delegating the subdomain to.

zone            host            type    data                    ttl
mx_priority     refresh         retry   expire  minimum         serial
   resp_person
-------------------------------------------------------------------------------------------------------------------------------------------------------------------
example.com     us              NS      ns10.example.com.       300     NULL
           NULL            NULL    NULL    NULL            NULL
 NULL
example.com     ns10            A       192.168.0.10            86400   NULL
           NULL            NULL    NULL    NULL            NULL
 NULL



On Server B:

Create an SOA record for us.example.com, an NS record for
us.boingo.comcontaining the ns10 server entry, and your new A record
entries.

zone            host            type    data                    ttl
mx_priority     refresh         retry   expire  minimum         serial
   resp_person
-------------------------------------------------------------------------------------------------------------------------------------------------------------------
us.example.com  @               SOA     ns10.example.com.       86400   NULL
           7200            600     86400   3600            1287000000
hostmaster.example.com.
us.example.com  us.example.com  NS      ns10.example.com.       300     NULL
           NULL            NULL    NULL    NULL            NULL
 NULL
us.example.com  www             A       192.168.0.110           86400   NULL
           NULL            NULL    NULL    NULL            NULL
 NULL
us.example.com  ftp             A       192.168.0.111           86400   NULL
           NULL            NULL    NULL    NULL            NULL
 NULL


This actually works for setting up sub-domain delegation in BIND-DLZ.  I
have tested it and verified working.  Let me know if you have any questions.

Thanks,

Mike
