Get a list of registered DNS Domains published by the DNS drivers:

GET /v1.1/<tenant_id>/os-floating-ip-dns/

# Sample Response: {'domain_entries' : [ {'domain': 'domain1.example.org', 'scope': 'public', 'project': 'proj1'} {'domain': 'domain2.example.net', 'scope': 'public', 'project': 'proj2'} {'domain': 'example.net', 'scope': 'public', 'project': ''} {'domain': 'example.internal', 'scope': 'private', 'availability_zone': 'zone1'}]}

Create or modify a DNS domain:

PUT /v1.1/<tenant_id>/os-floating-ip-dns/<domain>

# Sample body, public domain: {'domain_entry' : {'scope': 'public', 'project' : 'project1'}}

# Sample body, public (projectless) domain: {'domain_entry' : {'scope': 'public'}}

# Sample Response, public domain (success): {'domain_entry' : {'domain': 'domain1.example.org', 'scope': 'public', 'project': 'project1'}}

# Sample body, private domain: {'domain_entry' : {'scope': 'private', 'availability_domain': 'zone1'}}

# Sample Response, private domain (success): {'domain_entry' : {'domain': 'domain1.private', 'scope': 'private', 'availability_zone': 'zone1'}}

Failure Response Code: 403 (Insufficient permissions.)

Delete a DNS domain and all associated host entries:

DELETE /v1.1/<tenant_id>/os-floating-ip-dns/<domain>

Normal Response Code: 200 Failure Response Code: 404 (Domain to be deleted not found.) Failure Response Code: 403 (Insufficient permissions to delete.)

Create or modify a DNS entry:

PUT /v1.1/<tenant_id>/os-floating-ip-dns/<domain>/entries/<name>

# Sample body: { 'dns_entry' : { 'ip': '192.168.53.11', 'dns_type': 'A' }}

# Sample Response (success): { 'dns_entry' : { 'type' : 'A', 'name' : 'instance1' }}

Find unique DNS entry for a given domain and name:

GET /v1.1/<tenant_id>/os-floating-ip-dns/<domain>/entries/<name>

# Sample Response: { 'dns_entry' : { 'ip' : '192.168.53.11', 'type' : 'A', 'domain' : <domain>, 'name' : <name> }}

Find DNS entries for a given domain and ip:

GET /v1.1/<tenant_id>/os-floating-ip-dns/<domain>/entries?ip=<ip>

# Sample Response: { 'dns_entries' : [ { 'ip' : <ip>, 'type' : 'A', 'domain' : <domain>, 'name' : 'example1' } { 'ip' : <ip>, 'type' : 'A', 'domain' : <domain>, 'name' : 'example2' }]}
