| Summary | 0002265: GNS should delegate NS records | ||||
| Description | If no PKEY can be found for delegation but a NS record is present we should switch to a regular DNS query: Ex: www.tum.gnunet RR: tum NS ns.net.in.tum.de RR: tum LEHO tum.de RR: ns-net-in-tum-de.gnunet A someIP ( the glue ) Generate new name to lookup in DNS from LEHO: tum.de -> www.tum.de Send new DNS request to someIP (udp) for www.tum.de. The NS "glue" can be anything. A proper format needs to be determined. Especially since an additional namstore lookup is necessary like this. Can we directly put the IP in there? | ||||
| Tags | No tags attached. | ||||

Since NS takes precendence in the current resolver implementation anyway it probably makes senso to simplify the glue part: lookup www.tum.gnunet no pkey for tum in local zone but NS RR: tum NS tum.de <This is very similar to a LEHO> RR: tum A <IP of auth NS for tum.de> Now we can synthesize the DNS lookup name: www.tum.de and perform the lookup Advantage: Only a single lookup (for 'tum') in GNS is required. Since NS takes precendence over A because of delegation the query for tum.de A record will result in a DNS delegation! (Even though we have an A RR) |

Implemented as proposed above. Needs testing (and a test). The test should check if DNS delegation works properly. For example: CNAMEs into different zones: a.b.de -> server.c.com CNAME NS delegation |
