# 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" --config /home/achuprov/Documents/work/frostfs-dev-env/frostfs-adm.yml
|
||||
frostfs-adm morph nns register --name="sweden" --email="email@email.email" --config /home/achuprov/Documents/work/frostfs-dev-env/frostfs-adm.yml
|
||||
frostfs-adm morph nns register --name="org" --email="email@email.email" --config /home/achuprov/Documents/work/frostfs-dev-env/frostfs-adm.yml
|
||||
frostfs-adm morph nns register --name="animals.org" --email="email@email.email" --config /home/achuprov/Documents/work/frostfs-dev-env/frostfs-adm.yml
|
||||
```
|
||||
|
||||
Add the `cnametgt` records:
|
||||
|
||||
```
|
||||
frostfs-adm morph nns add-record --name="poland" --data="cnametgt=animals.org" --type="txt" --config /home/achuprov/Documents/work/frostfs-dev-env/frostfs-adm.yml
|
||||
frostfs-adm morph nns add-record --name="sweden" --data="cnametgt=animals.org" --type="txt" --config /home/achuprov/Documents/work/frostfs-dev-env/frostfs-adm.yml
|
||||
```
|
||||
|
||||
Create a domain with mapping to the global zone:
|
||||
|
||||
```
|
||||
frostfs-adm morph nns register --name="bober.poland" --email="email@email.email" --config /home/achuprov/Documents/work/frostfs-dev-env/frostfs-adm.yml
|
||||
```
|
||||
|
||||
Add any `TXT` record
|
||||
|
||||
```
|
||||
frostfs-adm morph nns add-record --name="bober.poland" --data="CID" --type="txt" --config /home/achuprov/Documents/work/frostfs-dev-env/frostfs-adm.yml
|
||||
```
|
||||
|
||||
Verify that the created domain has alias in the global zone
|
||||
|
||||
```
|
||||
frostfs-adm morph nns tokens -v --config /home/achuprov/Documents/work/frostfs-dev-env/frostfs-adm.yml

# NNS
|
||||
NNS - Neo Name Service is a service that allows manage a domain name as a digital asset (NFT). It has an interface similar to `DNS` but has significant differences in its internal structure.
|
||||
|
||||
## Entities:
|
||||
|
||||
- Domain
|
||||
- Record
|
||||
- Owner
|
||||
- Committee
|
||||
|
||||
### Domain
|
||||
|
||||
Domain is string that satisfies the following requirements:
|
||||
- Length from 2 to 255 characters.
|
||||
- Root domain must start with a letter.
|
||||
- All other fragments must start and end with a letter or digit.
|
||||
|
||||
Domain has owner, a registration period, and may optionally have records.
|
||||
|
||||
A fee established by the committee is charged upon domain registration. After registration, the owner can manage this asset (add/delete records, transfer ownership to another owner) until the end of the domain registration period.
|
||||
|
||||

|
||||
| CNAME | Represents canonical name record type |
|
||||
| SOA | Represents start of authority record type |
|
||||
|
||||

|
||||
|
||||
An owner is a wallet that has the right to manage this NFT (domain).
|
||||
|
||||
