Dear sir,
I appreciate your polite advice but I fear that your answer does not
resolve my problem; perhaps I was vague.
Internet Zahav provides us DNS services, it decides which server will be
authoritative for a given zone. I could independently create a reverse zone
but external clients will not be directed to my server since
it is not mentioned in the DNS tree. They must explicitly configure their
servers in a way that will redirect clients to our server.
Since we were assigned with only five addresses, Internet Zahav cannot delegate
control of the full zone. If it was possible to create a "partial" zone,
then Internet Zahav would be willing to transfer partial zone control to
our servers. The CNAME trick which I was referring to is:
The following is done in the ISP's side:
makif-omer NS dns.makif.omer.k12.il
31 CNAME 31.makif-omer.130.117.192.in-addr.arpa
32 CNAME 32.makif-omer.130.117.192.in-addr.arpa
33 CNAME 33.makif-omer.130.117.192.in-addr.arpa
34 CNAME 34.makif-omer.130.117.192.in-addr.arpa
35 CNAME 35.makif-omer.130.117.192.in-addr.arpa
Then I would simply setup on my side the makif-omer.130.117.192.in-addr.arpa
zone and poof, I have a partial zone. The above method is not extremely
aesthetic, so I was wondering whether a better way exists.
Best regards, Yotam Rubin
