# Globally unique domain zone
|
||||||
|
|
||||||
|
**Make sure you understand the [basic concepts](../nns/README.md) of `NNS`.**
|
||||||
|
|
||||||
|
`Globally Unique Domains Zone` (`GUDZ`) is an extension of `NNS` that ensures unique names across multiple domain zones. When this option is enabled, all newly created domains will automatically receive a corresponding alias in the designated global zone. Deleting a domain will also remove its alias from the global zone.
|
||||||
|
|
||||||
|
It's important to note that this feature is not retroactive: domains created before this option is enabled will not receive a global alias. Likewise, if the option is later disabled, domains that already have a `GUDZ` alias will retain their records. To fully disable `GUDZ`, all domains must be recreated with the option turned off.
|
||||||
|
|
||||||
|
To enable `GUDZ`, add a `cnametgt=$(global domain)` `TXT` record that specifies the global zone.
|
||||||
|
|
||||||
|
**Example:**
|
||||||
|
|
||||||
|
Domains:
|
||||||
|
- `poland`
|
||||||
|
- `sweden`
|
||||||
|
- `animals.org`
|
||||||
|
|
||||||
|
It is necessary to associate the domain zones `.poland` and `.sweden` into the global zone `.animals`.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Create domains:
|
||||||
|
|
||||||
|
```
|
||||||
|
frostfs-adm morph nns register --name="poland" --email="email@email.email"
|
||||||
|
frostfs-adm morph nns register --name="sweden" --email="email@email.email"
|
||||||
|
frostfs-adm morph nns register --name="org" --email="email@email.email"
|
||||||
|
frostfs-adm morph nns register --name="animals.org" --email="email@email.email"
|
||||||
|
```
|
||||||
|
|
||||||
|
Add the `cnametgt` records:
|
||||||
|
|
||||||
|
```
|
||||||
|
frostfs-adm morph nns add-record --name="poland" --data="cnametgt=animals.org" --type="txt"
|
||||||
|
frostfs-adm morph nns add-record --name="sweden" --data="cnametgt=animals.org" --type="txt"
|
||||||
|
```
|
||||||
|
|
||||||
|
Create a domain with mapping to the global zone:
|
||||||
|
|
||||||
|
```
|
||||||
|
frostfs-adm morph nns register --name="bober.poland" --email="email@email.email"
|
||||||
|
```
|
||||||
|
|
||||||
|
Add any `TXT` record
|
||||||
|
|
||||||
|
```
|
||||||
|
frostfs-adm morph nns add-record --name="bober.poland" --data="CID" --type="txt"
|
||||||
|
```
|
||||||
|
|
||||||
|
Verify that the created domain has alias in the global zone
|
||||||
|
|
||||||
|
```

|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
