ADR-0008: Host Naming and Site Codes #


Status	Accepted
Date	2026-09-04
Accepted	2026-09-05
Scope	How a host is named, and how a site is identified in that name and in DNS
Related	ADR-0002: Tenant Fabric Numbering — the site octet this record’s site codes sit alongside

Context #

Only the mobile site has hosts. Its names — hv01, core-rt01, provisioner-ph01 — are scoped to their site by inventory boundary alone, and the home site’s shell would reuse every one of them.

ADR-0005: Tenant Zone Apex Ownership

ADR-0005: Tenant Zone Apex Ownership #


Status	Accepted
Date	2026-09-03
Scope	Who owns the SOA and apex NS records inside a delegated tenant zone
Extends	ADR-0004: Tenant DNS Publication

Context #

ADR-0004 drew a clean line: the substrate creates the zone and issues the TSIG key, and the tenant writes the records inside it. Substrate provides the machine; tenants provide the content.

Building it exposed a category the line does not cover. A zone’s apex — its SOA, and the NS records naming the servers authoritative for it — is made of records, which puts it on the tenant side of that table. But it is created by pdnsutil create-zone, which is a substrate act, and it describes the zone’s own existence rather than anything the tenant runs. It is neither the machine nor the content.

ADR-0004: Tenant DNS Publication

Mon, 01 Jan 0001 00:00:00 +0000

ADR-0004: Tenant DNS Publication #


Status	Accepted
Date	2026-09-01
Scope	How a tenant’s own DNS records reach the resolver substrate clients use
Depends on	ADR-0001: Tenant Network Fabric, ADR-0002: Tenant Fabric Numbering
Extended by	ADR-0005: Tenant Zone Apex Ownership — the zone apex, which §4 does not assign
Extended by	ADR-0006: Tenant Code Boundary — where the tenant’s code lives, which §5 does not say
Extended by	ADR-0010: Tenants Consume Platform Services — §5’s line as a rule for every platform service, not only DNS

Context #

Seam 2 of ADR-0001 splits addressing from naming: IPAM belongs to the fabric, while DNS is tenant-owned but published to the substrate zone. With ADR-0003 closing egress, this is the last part of the tenant contract still undecided.
