<font style="font-size: 10pt;" face="Calibri" size="2"><span style="font-size:11pt"><div>Dear all,</div>
<div> </div>
<div>I have tried to configure a zone containing a range of IPV6 PTR records.</div>
<div>My target was to see how it is possible to configure such a zone to
always return the same answer for all the IPV6 IP’s in the range.</div>
<div>And if possible to return specifi names for specific IP’s.</div>
<div> </div>
<div><u>Example of a IPV6 range:</u></div>
<div> </div>
<div>1234:5678:90ab:00cd::/56</div>
<div> </div>
<div> </div>
<div><b><u>Creation of the zone </u></b><font face="Wingdings">è</font><b><u> “0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa.”</u></b></div>
<div> </div>
<div>In the zone, I have put the following PTR record:</div>
<div> </div>
<div>*.0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. 3600 IN PTR 123.lebrol.be.</div>
<div> </div>
<div>It seems (according to some of my tests) that for all IP’s in the range, the reverse is “123.lebrol.be.”</div>
<div> </div>
<div>Question <font face="Wingdings">è</font> is this a correct way to configure reverse IPV6 if we accept the same name for all the IP’s in the range?</div>
<div> </div>
<div> </div>
<div><b><u>Zone modification:</u></b></div>
<div> </div>
<div>I have tried to add in the zone file the possibility to answer a
specific name to a specific IP in the range and keep answering the
general name to all the other IP’s in the range.</div>
<div> </div>
<div>*.0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. 3600 IN PTR 123.lebrol.be.</div>
<div>1.2.3.4.5.6.7.8.9.a.b.c.d.e.f.0.<font color="red"><b>1.2</b></font>.0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. 3600 IN PTR nombre.de.cerise.be. <font face="Wingdings">è</font> specific IP</div>
<div> </div>
<div> </div>
<div>It works when the specific IP is used:</div>
<div> </div>
<div>lennydnstest01:~# dig @localhost -x 1234:5678:90ab:0021:0fed:cba9:8765:4321</div>
<div> </div>
<div>;; QUESTION SECTION:</div>
<div>;1.2.3.4.5.6.7.8.9.a.b.c.d.e.f.0.1.2.0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. IN PTR</div>
<div>;; ANSWER SECTION:</div>
<div>1.2.3.4.5.6.7.8.9.a.b.c.d.e.f.0<b>.</b>1.2<font color="red">.</font>0.0.b.a.0.9.8.7.6.5.4.3.2.1.ip6.arpa. 3600 IN PTR nombre.de.cerise.be.</div>
<div> </div>
<div> </div>
<div>But if another IP in the range is used having the following nibbles mapping the specific PTR (here <font color="red"><b>1.2</b></font> ), it do not work <font style="" face="Wingdings">and</font> nothing is found!</div>
<div> </div>
