Title: MSDCS DNS issues
Post by: dazza76 on October 15, 2020, 02:53:03 am
We currently have 2 instances in a cluster .
both boxes have 2 interfaces an internal one for comms and an external one .
what we have noticed is when we query the dns both IP's appear in the query. how can we either exclude the external interface or ip ( it is a martian address)
we also note loopback addresses that are not 127.0.0.1 ar also advertised.

dig ad1.test.local
;; ANSWER SECTION:
ad1.test.local. 900 IN A 192.168.1.1    #internal for comms
ad1.test.local. 900 IN A 192.0.0.1       #external only no inter comms allowed firewalled
ad1.test.local. 900 IN A 192.0.255.1       #loopback test

dig ad2.test.local
;; ANSWER SECTION:
ad1.test.local. 900 IN A 192.168.1.2    #internal for comms
ad1.test.local. 900 IN A 192.0.2.2       #external only no inter comms allowed firewalled
ad1.test.local. 900 IN A 192.0.255.1       #loopback test
