Greetings,
does the following setup violate any DNS RFCs or is it in the conflict
with any best practices?
----------------------------------------------------------------------
[and...@strigidae ~]$ dig +nocmd +nocom +noque +nosta domain1.tld1. ns
domain1.tld1. 86400 IN NS ns1.domain1.tld1.
domain1.tld1. 86400 IN NS ns2.domain1.tld1.
domain1.tld1. 86400 IN NS ns1.domain2.tld2.
domain1.tld1. 86400 IN NS ns2.domain2.tld2.
domain1.tld1. 86400 IN NS ns1.domain3.tld3.
domain1.tld1. 86400 IN NS ns2.domain3.tld3.
ns1.domain1.tld1. 86400 IN A IP.Add.ress.1
ns2.domain1.tld1. 86400 IN A IP.Add.ress.2
^^^^^^^^^^^^^
ns1.domain2.tld2. 86400 IN A IP.Add.ress.3
^^^^^^^^^^^^^
ns2.domain2.tld2. 86400 IN A IP.Add.ress.4
ns1.domain3.tld3. 86400 IN A IP.Add.ress.2
^^^^^^^^^^^^^
ns2.domain3.tld3. 86400 IN A IP.Add.ress.3
^^^^^^^^^^^^^
----------------------------------------------------------------------
As we can see above, the ns2.domain1.tld1 / ns1.domain3.tld3 are
actually the same physical host with the IP.Add.ress.2 and the
ns1.domain2.tld2 / ns2.domain3.tld3 are actually the same machine with
the IP.Add.ress.3.
What are the benefits of this setup?
Thanks in advance.
