| 1 | IP Reverse Delegation |
|---|
| 2 | ===================== |
|---|
| 3 | |
|---|
| 4 | Before you start you need to change a parameter in /usr/local/etc/unbound/unbound.conf: |
|---|
| 5 | |
|---|
| 6 | # a number of locally served zones can be configured. |
|---|
| 7 | # local-zone: "10.10.in-addr.arpa." nodefault |
|---|
| 8 | local-zone: "10.in-addr.arpa." transparent |
|---|
| 9 | |
|---|
| 10 | Then reload the unbound server: |
|---|
| 11 | |
|---|
| 12 | # unbound-control reload |
|---|
| 13 | |
|---|
| 14 | On your servers auth1, auth2 and resolv you have an IPv4 and an IPv6 address. You should |
|---|
| 15 | make sure you have entries for each of these in your forward file. |
|---|
| 16 | e.g. |
|---|
| 17 | |
|---|
| 18 | auth1.MYTLD. IN A 10.10.X.1 |
|---|
| 19 | IN AAAA 2400:4136:8b5f:3a11::X:1 |
|---|
| 20 | auth2.MYTLD. IN A 10.10.X.2 |
|---|
| 21 | IN AAAA 2400:4136:8b5f:3a11::X:2 |
|---|
| 22 | resolv.MYTLD. IN A 10.10.X.3 |
|---|
| 23 | IN AAAA 2400:4136:8b5f:3a11::X:3 |
|---|
| 24 | |
|---|
| 25 | Don't forget to replace 'MYTLD' with your own domain (unless your name is Annie!) |
|---|
| 26 | |
|---|
| 27 | Adding the zones |
|---|
| 28 | ---------------- |
|---|
| 29 | |
|---|
| 30 | 1. You should create a zone file for your in-addr.arpa zone and for your ip6.arpa zone |
|---|
| 31 | using the names: |
|---|
| 32 | |
|---|
| 33 | db.X.10.10.in-addr.arpa |
|---|
| 34 | db.X.0.0.0.0.0.0.0.0.0.0.0.1.1.a.3.f.5.b.8.6.3.1.4.0.0.4.2.ip6.arpa |
|---|
| 35 | |
|---|
| 36 | You should copy the SOA and NS records from your MYTLD file to these files. |
|---|
| 37 | |
|---|
| 38 | 2. You will need to add a zone statement to the named.conf file on auth1 and the nsd.conf |
|---|
| 39 | file on auth2. Use the existing details for your MYTLD as a template. |
|---|
| 40 | |
|---|
| 41 | 3. On the parent server the following delegations have been set up already |
|---|
| 42 | |
|---|
| 43 | Your in-addr.arpa delegations are: |
|---|
| 44 | |
|---|
| 45 | 1.10.10.in-addr.arpa. IN NS auth1.grp1.dns.nsrc.org. |
|---|
| 46 | IN NS auth2.grp1.dns.nsrc.org. |
|---|
| 47 | |
|---|
| 48 | 2.10.10.in-addr.arpa. IN NS auth1.grp2.dns.nsrc.org. |
|---|
| 49 | IN NS auth2.grp2.dns.nsrc.org. |
|---|
| 50 | |
|---|
| 51 | 3.10.10.in-addr.arpa. IN NS auth1.grp3.dns.nsrc.org. |
|---|
| 52 | IN NS auth2.grp3.dns.nsrc.org. |
|---|
| 53 | |
|---|
| 54 | 4.10.10.in-addr.arpa. IN NS auth1.grp4.dns.nsrc.org. |
|---|
| 55 | IN NS auth2.grp4.dns.nsrc.org. |
|---|
| 56 | |
|---|
| 57 | 5.10.10.in-addr.arpa. IN NS auth1.grp5.dns.nsrc.org. |
|---|
| 58 | IN NS auth2.grp5.dns.nsrc.org. |
|---|
| 59 | |
|---|
| 60 | 6.10.10.in-addr.arpa. IN NS auth1.grp6.dns.nsrc.org. |
|---|
| 61 | IN NS auth2.grp6.dns.nsrc.org. |
|---|
| 62 | |
|---|
| 63 | 7.10.10.in-addr.arpa. IN NS auth1.grp7.dns.nsrc.org. |
|---|
| 64 | IN NS auth2.grp7.dns.nsrc.org. |
|---|
| 65 | |
|---|
| 66 | 8.10.10.in-addr.arpa. IN NS auth1.grp8.dns.nsrc.org. |
|---|
| 67 | IN NS auth2.grp8.dns.nsrc.org. |
|---|
| 68 | |
|---|
| 69 | Your ip6.arpa delegations are: |
|---|
| 70 | 1.0.0.0.0.0.0.0.0.0.0.0.1.1.a.3.f.5.b.8.6.3.1.4.0.0.4.2.ip6.arpa. IN NS auth1.grp1.dns.nsrc.org. |
|---|
| 71 | IN NS auth2.grp1.dns.nsrc.org. |
|---|
| 72 | |
|---|
| 73 | 2.0.0.0.0.0.0.0.0.0.0.0.1.1.a.3.f.5.b.8.6.3.1.4.0.0.4.2.ip6.arpa. IN NS auth1.grp2.dns.nsrc.org. |
|---|
| 74 | IN NS auth2.grp2.dns.nsrc.org. |
|---|
| 75 | |
|---|
| 76 | 3.0.0.0.0.0.0.0.0.0.0.0.1.1.a.3.f.5.b.8.6.3.1.4.0.0.4.2.ip6.arpa. IN NS auth1.grp3.dns.nsrc.org. |
|---|
| 77 | IN NS auth2.grp3.dns.nsrc.org. |
|---|
| 78 | |
|---|
| 79 | 4.0.0.0.0.0.0.0.0.0.0.0.1.1.a.3.f.5.b.8.6.3.1.4.0.0.4.2.ip6.arpa. IN NS auth1.grp4.dns.nsrc.org. |
|---|
| 80 | IN NS auth2.grp4.dns.nsrc.org. |
|---|
| 81 | |
|---|
| 82 | 5.0.0.0.0.0.0.0.0.0.0.0.1.1.a.3.f.5.b.8.6.3.1.4.0.0.4.2.ip6.arpa. IN NS auth1.grp5.dns.nsrc.org. |
|---|
| 83 | IN NS auth2.grp5.dns.nsrc.org. |
|---|
| 84 | |
|---|
| 85 | 6.0.0.0.0.0.0.0.0.0.0.0.1.1.a.3.f.5.b.8.6.3.1.4.0.0.4.2.ip6.arpa. IN NS auth1.grp6.dns.nsrc.org. |
|---|
| 86 | IN NS auth2.grp6.dns.nsrc.org. |
|---|
| 87 | |
|---|
| 88 | 7.0.0.0.0.0.0.0.0.0.0.0.1.1.a.3.f.5.b.8.6.3.1.4.0.0.4.2.ip6.arpa. IN NS auth1.grp7.dns.nsrc.org. |
|---|
| 89 | IN NS auth2.grp7.dns.nsrc.org. |
|---|
| 90 | |
|---|
| 91 | 8.0.0.0.0.0.0.0.0.0.0.0.1.1.a.3.f.5.b.8.6.3.1.4.0.0.4.2.ip6.arpa. IN NS auth1.grp8.dns.nsrc.org. |
|---|
| 92 | IN NS auth2.grp8.dns.nsrc.org. |
|---|
| 93 | |
|---|
| 94 | 4. Use dig to check that the nameservers are delegated properly after you reload your servers. |
|---|
| 95 | |
|---|
| 96 | 5. Add PTR records to each of the zone files for each of your three servers. |
|---|
| 97 | |
|---|
| 98 | e.g. |
|---|
| 99 | |
|---|
| 100 | 1 PTR auth1.MYTLD. |
|---|
| 101 | |
|---|
| 102 | and |
|---|
| 103 | |
|---|
| 104 | 1.0.0.0 PTR auth1.MYTLD. |
|---|
| 105 | |
|---|
| 106 | and so on. |
|---|
| 107 | |
|---|
| 108 | 6. Check that the reverse lookup works using "dig -x" |
|---|
