| 1 | Now we would like to do the following: |
|---|
| 2 | |
|---|
| 3 | 1. Make our nameservers listen on IPv6 |
|---|
| 4 | 2. Add v6 addresses to the nameservers in our zone, so they can receive |
|---|
| 5 | v6 traffic |
|---|
| 6 | 3. Add v6 addresses to the host records, for example "www AAAA", |
|---|
| 7 | etc... |
|---|
| 8 | |
|---|
| 9 | |
|---|
| 10 | 1. Make our nameservers listen on IPv6 |
|---|
| 11 | |
|---|
| 12 | a) on "auth1.grpX (BIND)'s named.conf, in the options section, add: |
|---|
| 13 | |
|---|
| 14 | listen-on-v6 { any; }; |
|---|
| 15 | |
|---|
| 16 | (Remember to restart named!) |
|---|
| 17 | |
|---|
| 18 | b) on "resolv.grpX" (Unbound)'s unbound.conf, in the "server:" section, add |
|---|
| 19 | the following parameters (in the correct locations - if necessary, |
|---|
| 20 | search in the configuration file to place them correctly) |
|---|
| 21 | |
|---|
| 22 | do-ip6: yes |
|---|
| 23 | interface: ::0 |
|---|
| 24 | interface: 0.0.0.0 |
|---|
| 25 | access-control: fdba:dc55:48c7::/64 allow |
|---|
| 26 | |
|---|
| 27 | (Remember to restart unbound!) |
|---|
| 28 | |
|---|
| 29 | c) on "auth1.grpX" (NSD), edit nsd.conf, and in the "server:" section, add |
|---|
| 30 | the following parameters: |
|---|
| 31 | |
|---|
| 32 | ip-address: fdba:dc55:48c7::XX:YY |
|---|
| 33 | |
|---|
| 34 | (remember to replace XX:YY with your group and IP for the auth server) |
|---|
| 35 | |
|---|
| 36 | 2. Now, we need to test that all your machines have IPv6 addresses in the DNS |
|---|
| 37 | |
|---|
| 38 | Your machines are called : |
|---|
| 39 | |
|---|
| 40 | auth1.grpX.dns.nsrc.org |
|---|
| 41 | resolv.grpX.dns.nsrc.org |
|---|
| 42 | auth2.grpX.dns.nsrc.org |
|---|
| 43 | |
|---|
| 44 | Since they are in the "dns.nsrc.org" zone, you don't need to do anything here :) |
|---|
| 45 | The instructor will modify the dns.nsrc.org zone, and add the v6 address you |
|---|
| 46 | have configured on eth0, to the DNS record for "auth1.grpX.dns.nsrc.org" and |
|---|
| 47 | "auth1.grpX.dns.nsrc.org" and "resolv.grpX.dns.nsrc.org". |
|---|
| 48 | |
|---|
| 49 | But test that you can "dig AAAA auth1.grpX.dns.nsrc.org" and see what |
|---|
| 50 | you get... |
|---|
| 51 | |
|---|
| 52 | |
|---|
| 53 | 3. Add IPv6 records (AAAA) for the names in your zone, like www, etc... |
|---|
| 54 | |
|---|
| 55 | You will need to add IPv6 AAAA records to all your hosts |
|---|
| 56 | you find in your zones. If they have an A record, also add the |
|---|
| 57 | corresponding AAAA record. |
|---|
| 58 | |
|---|
| 59 | You can then start to use dig and see if you can find some |
|---|
| 60 | TLDs in the class that have AAAA records for their "www" host, |
|---|
| 61 | for their NSes, etc... |
|---|
| 62 | |
|---|
| 63 | 4. Try and ping other people's hosts in the room using v6. |
|---|
| 64 | |
|---|
| 65 | Use dig to connect to other people's nameservers, and verify that |
|---|
| 66 | they: |
|---|
| 67 | |
|---|
| 68 | - answer in IPv6 |
|---|
| 69 | - have an IPv6 record for their name |
|---|
| 70 | - provide DNS answer with IPv6 addresses! |
|---|
| 71 | |
|---|
| 72 | Some sample commands: |
|---|
| 73 | |
|---|
| 74 | |
|---|
| 75 | # dig AAAA auth1.grpX.dns.nsrc.org |
|---|
| 76 | |
|---|
| 77 | Try and ping these hosts: |
|---|
| 78 | |
|---|
| 79 | # ping6 auth1.dns.nsrc.org |
|---|
| 80 | # ping6 auth2.dns.nsrc.org |
|---|
| 81 | # ping6 auth1.grpX.dns.nsrc.org |
|---|
| 82 | |
|---|
| 83 | Try performing DNS queries in v6 against auth1 + auth2: |
|---|
| 84 | |
|---|
| 85 | # dig -6 @auth1.dns.nsrc.org dns.nsrc.org ns |
|---|
| 86 | # dig -6 @auth2.dns.nsrc.org dns.nsrc.org ns |
|---|
| 87 | |
|---|
| 88 | |
|---|
| 89 | |
|---|
| 90 | |
|---|
| 91 | *** ABOUT GLUE RECORDS AND IPv6 *** |
|---|
| 92 | *** THIS SECTION IS ONLY RELEVANT IF YOU HAVE DECLARED DNS *** |
|---|
| 93 | *** SERVERS WITH NAMESERVERS *INSIDE* YOUR ZONE, E.G. *** |
|---|
| 94 | *** "NS.MYTLD." INSTEAD OF "AUTH1.GRPX.DNS.NSRC.ORG" *** |
|---|
| 95 | |
|---|
| 96 | |
|---|
| 97 | For example, in the parent zone 'nsrc.org' we have: |
|---|
| 98 | |
|---|
| 99 | dns.nsrc.org. NS auth1.dns.nsrc.org. |
|---|
| 100 | NS auth2.dns.nsrc.org. |
|---|
| 101 | |
|---|
| 102 | Since auth1.ws and auth2.ws are IN the zone being |
|---|
| 103 | delegated, then we need to add glue records! |
|---|
| 104 | |
|---|
| 105 | ; v4 GLUE records |
|---|
| 106 | auth1.dns.nsrc.org. A 10.20.0.234 |
|---|
| 107 | auth2.dns.nsrc.org. A 10.20.0.235 |
|---|
| 108 | |
|---|
| 109 | In the same way, we will need IPbv6 glue records: |
|---|
| 110 | |
|---|
| 111 | ; v6 GLUE records |
|---|
| 112 | auth1.dns.nsrc.org. AAAA fdba:dc55:48c7::234 |
|---|
| 113 | auth2.dns.nsrc.org. AAAA fdba:dc55:48c7::235 |
|---|
| 114 | |
|---|
| 115 | In the child zone 'dns.nsrc.org', we will need to declare these |
|---|
| 116 | hosts as well. In fact, as explained in class, you MUST declare |
|---|
| 117 | them otherwise you will experience strange problems with resolution: |
|---|
| 118 | |
|---|
| 119 | dns.nsrc.org. SOA ... |
|---|
| 120 | |
|---|
| 121 | NS auth1 |
|---|
| 122 | NS auth2 |
|---|
| 123 | |
|---|
| 124 | auth1 A 10.20.0.234 |
|---|
| 125 | AAAA fdba:dc55:48c7::234 |
|---|
| 126 | auth2 A 10.20.0.235 |
|---|
| 127 | AAAA fdba:dc55:48c7::235 |
|---|
| 128 | |
|---|
| 129 | In your zone "MYTLD", you MAY or MAY NOT have used NSes IN your zone. |
|---|
| 130 | |
|---|
| 131 | - If you did (i.e.: ns1.MYTLD for example) |
|---|
| 132 | |
|---|
| 133 | ... then you need to ADD the IPv6 records for the nameservers you declared, |
|---|
| 134 | the same way we have done for auth1 and auth2. |
|---|
