Hello,

I have few questions, basically i need to get few thing get straight...

First of all, whats the difference between /48 and /64, i can see that /48 is shorter...

Second thing, I pointed some domain on my ipv6 like this

q@blabla:~$ host sub.domain.cc
sub.domain.cc has IPv6 address 2001:470:1f0a:1e6::3

I also changed Name Server 1,2,3 to correct ones.

So when i do
$ host 2001:470:1f0a:1e6::3
i get
Host 3.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.6.e.1.0.a.0.f.1.0.7.4.0.1.0.0.2.ip6.arpa not found: 3(NXDOMAIN)


im running bind on my own server...
heres the conf of it


--- Code: ---;

Basically a /48 lets you easily subnet out multiple /64 allocations for your network.
So for example, if you are operating a router with multiple interfaces for different LANs on your network, you can allocate a /64 per LAN out of your larger /48 allocation to each interface.

As mentioned in other threads: rDNS for the /64 used for the tunnel's point-to-point connection is not delegated to you, only rDNS for the routed /64 and /48 allocations.
In this case your routed /64 is "1f0b" not "1f0a".

qstraza:
thanks for explaining.

So if you dont mind helping me, I have a non-tunnel issue then...

I can ping6 from this site


--- Code: ---Ping6 result:

PING 2001:470:1f0b:1e6::3(2001:470:1f0b:1e6::3) 56 data bytes

--- 2001:470:1f0b:1e6::3 ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4035ms
rtt min/avg/max/mdev = 212.944/261.036/288.020/26.540 ms

--- End code ---

So I think, that i set this right, so my revDNS doesnt work and i dont know why.


--- Code: ---q@lj:~$ host q.smajdek.si
q.smajdek.si has IPv6 address 2001:470:1f0b:1e6::3

--- End code ---


--- Code: ---q@lj:~$ host 2001:470:1f0b:1e6::3
;; connection timed out; no servers could be reached

--- End code ---

and my bind conf:


--- Code: ---;
; 2001:470:1f0b:1e6::/64
;
$TTL 3d ; Default TTL (bind 8 needs this, bind 9 ignores it)
@       IN SOA 6.e.1.0.b.0.f.1.0.7.4.0.1.0.0.2.ip6.arpa. mejl (

                24h             ; Refresh time
                30m             ; Retry time
                2d              ; Expire time
                3d              ; Default TTL (bind 8 ignores this, bind 9 needs it)
)

                                ; Name server entries
                                IN     NS     hostname.
                                IN     NS     ns1.afraid.org.
                                IN     NS     ns2.afraid.org.
; IPv6 PTR entries

; Subnet #1
$ORIGIN 6.e.1.0.b.0.f.1.0.7.4.0.1.0.0.2.ip6.arpa.

3.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0         IN      PTR     q.smajdek.si.

--- End code ---

Am I missing something?

broquea:
Right off the bat, comparing to one of my bind rdns zones, it looks fine.

Looking at the serial, its set for a date a few weeks ago. If you've made any changes in the zone file since then (like 1f0a to 1f0b) have you incremented the serial?

kriteknetworks:
q@lj:~$ host 2001:470:1f0b:1e6::3
;; connection timed out; no servers could be reached

Is bind running? is it listening on the correct interface(s)?
