However a gateway is still set. (Purpose is to create a HA network between 2 servers, where only HA heartbeat is sent between 2 nodes).\n\n## Steps to reproduce\n\n\n```python\n\napiclient = IaasApi(_api_configuration)\nipv4withprefix = CreateNetworkIPv4WithPrefix(prefix = '10.1.0.0/28', nameservers = [ '8.8.8.8' ])\nprint(ipv4withprefix)\n###\n### gateway=None nameservers=['8.8.8.8'] prefix='10.1.0.0/28'\n###\n\nipv4 = CreateNetworkIPv4(ipv4withprefix)\nprint(ipv4)\n###\n### oneof_schema_1_validator=None oneof_schema_2_validator=None actual_instance=CreateNetworkIPv4WithPrefix(gateway=None, nameservers=['8.8.8.8'], prefix='10.1.0.0/28') one_of_schemas={'CreateNetworkIPv4WithPrefix', 'CreateNetworkIPv4WithPrefixLength'}\n###\n\ncandidateitem = CreateNetworkPayload(name = name, ipv4 = ipv4, routed = False, dhcp = True)\nprint(candidateitem)\n###\n### dhcp=True ipv4=CreateNetworkIPv4(oneof_schema_1_validator=None, oneof_schema_2_validator=None, actual_instance=CreateNetworkIPv4WithPrefix(gateway=None, nameservers=['8.8.8.8'], prefix='10.1.0.0/28'), one_of_schemas={'CreateNetworkIPv4WithPrefix', 'CreateNetworkIPv4WithPrefixLength'}) ipv6=None labels=None name='ihe01testnetwork' routed=False routing_table_id=None\n###\n\nresult = apiclient.create_network(project_id=project_id, region=region, create_network_payload=candidateitem)\nprint(result)\n###\n### created_at=datetime.datetime(2026, 1, 20, 15, 37, 7, tzinfo=TzInfo(0)) dhcp=True id='c90cdb22-202a-46b2-b224-e268ec48e46c' ipv4=NetworkIPv4(gateway=None, nameservers=['8.8.8.8'], prefixes=['10.1.0.0/28'], public_ip=None) ipv6=None labels={} name='ihe01testnetwork' routed=False routing_table_id=None status='CREATING' updated_at=datetime.datetime(2026, 1, 20, 15, 37, 7, tzinfo=TzInfo(0))\n###\n### ---\u003e while creating, gateway is still None\n\nresult2 = apiclient.get_network(project_id=project_id, region=region, network_id='c90cdb22-202a-46b2-b224-e268ec48e46c')\nprint(result2)\n###\n### created_at=datetime.datetime(2026, 1, 20, 15, 37, 7, tzinfo=TzInfo(0)) dhcp=True id='c90cdb22-202a-46b2-b224-e268ec48e46c' ipv4=NetworkIPv4(gateway='10.1.0.1', nameservers=['8.8.8.8'], prefixes=['10.1.0.0/28'], public_ip=None) ipv6=NetworkIPv6(gateway=None, nameservers=[], prefixes=[]) labels={} name='ihe01testnetwork' routed=False routing_table_id=None status='CREATED' updated_at=datetime.datetime(2026, 1, 20, 15, 37, 10, tzinfo=TzInfo(0))\n###\n\n### ---\u003e once created, gateway is set, although it shall be NONE.\n\n```\n\n\u003c!-- Please provide us with the steps to reproduce the behavior. --\u003e\n\n1. Initialize the API\n2. Create a network with non_routed=True and ipv4.gateway=None\n3. Get details after network creation has completed\n\n## Actual behavior\n\nShows a gateway is assigned to subnet, and communicated i.e. to DHCP clients\n\n## Expected behavior\n\nNetwork has no gateway, no gateway is communicated via DHCP.\n\n## Environment\n```\nstackit-core==0.2.0\nstackit-iaas==1.1.0\n```\n\n\n## Additional info\nAddon: Also via stackit CLI this seems to not work.... option `no-ipv4-gateway` seems to be ignored? Although network-interface list shows that there is no gateway interface from the project router (only the meta interface), the network overview still shows the gateway IP.\n\n```\nstackit network create --name ihe01testnetwork --non-routed --no-ipv4-gateway --ipv4-prefix \"10.1.0.0/28\"\n\nstackit network describe 83957c75-4218-48b7-af25-5ed22960ae1b\n\n ID                │ 83957c75-4218-48b7-af25-5ed22960ae1b\n───────────────────┼──────────────────────────────────────\n NAME              │ ihe01testnetwork\n───────────────────┼──────────────────────────────────────\n STATE             │ CREATED\n───────────────────┼──────────────────────────────────────\n ROUTED            │ false\n───────────────────┼──────────────────────────────────────\n IPv4 GATEWAY      │ 10.1.0.1\n───────────────────┼──────────────────────────────────────\n IPv4 NAME SERVERS │ 208.67.222.222, 208.67.220.220\n───────────────────┼──────────────────────────────────────\n IPv4 PREFIXES     │ 10.1.0.0/28\n```\n\n","author":{"url":"https://github.com/cldmkr","@type":"Person","name":"cldmkr"},"datePublished":"2026-01-20T15:51:10.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/2841/stackit-sdk-python/issues/2841"}
