Creating Parking Page through Name servers

king dev · 05-15-2018, 10:52 AM

Hello,

i want to create a DNS server to host all expired domain names with Custom Page.

So when domain expire, the DNS change to expired1.exemple.com, expired2.exemple.com

the server who host those DNS will show a Custom Page created by me.

Do you have an idea how to do that.

Custom Page implies a web server not a DNS server (though they can be on the same server).

If it is an "expired" domain it won't matter if you have a page for it as no traffic would go to it since it would no longer resolve to your DNS server after the root servers no longer see it as valid.

Most of the Registrars DO point to an expiration page for a short period of time after registration expires to give you a grace period to renew the registration but prevent traffic from going to your real web page during that grace period.

i'am a cctld registrar, all of our domains remains active for 30 days.

Do you have an idea to do that:

every domain point to expired1.myvompany.com, expired2.myvompany.com will show the custom page

We aren't a Registrar.

What I have seen Registrars do when we allow domains to expire is they change the name servers of the domain to something like:
ns1.pendingdeletion.com & ns2.pendingdeletion.com or if parked to ns1.parked.com and ns2.parked.com. I imagine that is simpler than changing other records. What they do behind the scenes after changing the Name Servers I can't say.

You could just set up an alias zone file then update your named.conf on those servers to add each of the zones to that alias zone. In the alias zone file you could have it point to a single IP then insure your web server accepts all the zone URLs (e.g. expirezone1.example.com, expiredzone2.example.com etc... along with www for each.

So for BIND DNS servers (I set name of domain YOU use to expiredzones.com - you would of course change it to the real zone
you use and edit the name servers and MX (if desired) accordingly.)

Zone file expiredzone-aliases:

Code:

@               IN SOA  ns1.expiredzones.com. admin.expiredzones.com. (
                        2018051501      ; serial number
                        7200            ; refresh
                        3600            ; retry
                        604800          ; expire
                        2400 )          ; Minimum TTL


; Name Servers
;
                IN NS   ns1.expiredzones.com.
                IN NS   ns2.expiredzones.com.
;
; Mail Servers
        300     IN MX   20  smtp.expiredzones.com.
;
;
; Addresses (A records) - Point to the IP of the web server
;
localhost       IN A    127.0.0.1
;
@               IN A    x.x.x.x ; Web server IP
www             IN A    x.x.x.x ; Same web server IP
;

And in named.conf (in addition to the normal stuff):

Code:

zone "expiredzone1.com" {
        type master;
        file "expiredzone-aliases";
        allow-query { any; };
};

zone "expiredzone2.com" {
        type master;
        file "expiredzone-aliases";
        allow-query { any; };
};

In the above zone file "@" is used instead of actual expired domain names so that it gets replaced with the expired domain names from named.conf when they are queried. (e.g. @ becomes "expiredzone1.com" if someone is querying that but becomes expiredzone2.com if someone is instead querying that. This simplifies setup so that you only need one zone file for multiple domains (which are called zones in named.conf - zone and zonefile can be and often are different as shown in my example).
