How DO I? Setup RDNS

[zmenchhofer]

To set up RDNS you need to have your IP’s Delegated to you from FDC then you need to add it to named.conf and you will need to also create a new PTR for each IP range
Lets say you have a Class C address and you have 66.90.111.50-75 you will need to add a line like this to named.conf

zone "111.90.66.in-addr.arpa" IN {
type master;
file "/var/named/66.90.111.db";
allow-update { none; };
};

Then you will need to create a new zone file something like this

$TTL 86400
@ IN SOA ns1.yourhost.com. yourcontact.emailaddress.com. (
2005021601 ; serial
28800 ; refresh
14400 ; retry
3600000 ; expire
86400 ; ttl
)
IN NS ns.yourhost.com.
50 IN PTR WhatEverYouWant.Com.
51 IN PTR WhatEverYouWant.Com.
52 IN PTR WhatEverYouWant.Com.
53 IN PTR WhatEverYouWant.Com.
54 IN PTR WhatEverYouWant.Com.
55 IN PTR WhatEverYouWant.Com.

And so on…..

Any questions just ask!

Does this means that if you do this, when you go to IRC, your host will be listed as the one you specified such as 50 IN PTR WhatEverYouWant.Com? Kinda reverse dns spoofing huh?

[mikron15]

You can only apply Rdns for the ips u own, and yes, u can make it resolve whatever u want

[SiD]

And how bout IPv6 RDnS ? can someone shed some light on that ?



cheers

[chandro]

Thx zmenchhofer.

If I have the domains' dns managed at dnsmadeeasy, should the reverse dns be done at the server or at dnsmadeeasy?

[zmenchhofer]

depends where you have the ips delegated to

[allanite]

if I have ips delegated,
do I do the reverse dns on my server here at FDC or
I do the reverse dns at dnsmadeeasy the service I use for my dns management for alll my domains but
my server is running dns and bind?

Thx
