We are hosting our own dns server our scenario is as under;
dns
ip: a.b.c.1
fqdn:ns1.example.com ------> reverse lookup to a.b.c.1
mail server
ip a.b.c.2
mail.example.com ------> reverse lookup to a.b.c.2
smtp.example.com ------> no reverse lookup
pop.example.com ------> no reverse lookup
web server
ip a.b.c.3
example.com ------> reverse lookup to a.b.c.3
www.example.com ------> no reverse lookup
a few days back our dns server ip got blacklisted and all our services were down from outside. We had also added a new dns server on a separate network that caused our domain and machines with same names as above to resolve on different ips, can this b a cause of being blacklisted?
But all blacklists points towards spamming.
Can anyone please explain why my dns ip got blacklisted instead of my email or web server ip?
