All Node Providers are requested to deploy at least one node in their data center with IPv4.

Node Providers are able to add, update, or remove a node’s IPv4 and domain name configuration in one of two ways:

  • Method #1: IC-OS installation image configuration (redeployment required)
    • This method is designed for nodes that onboarded using a Nitrokey HSM.
  • Method #2: dfx commands (no redeployment required)
    • This method is designed for nodes that onboarded without using a Nitrokey HSM.


Requirements

Method #1: Configure IPv4 via IC-OS Installation (redeployment required)

To redeploy a node with IPv4 and domain name configuration, follow the node deployment guide of your choice, making sure to add the IPv4 and domain name configuration in step 6:

Please note that you must reconfigure the IC-OS installation image for every IPv4 node you deploy. This means that you cannot use a single IC-OS installation image to deploy multiple nodes like you are able to do when just configuring IPv6 nodes. After each IPv4 node deployment, you must plug your IC-OS Installation USB stick back into your laptop and return to step 6 in the node deployment guide to reconfigure your installation image.

Method #2: Configure IPv4 via dfx (no redeployment required)

  1. Obtain your node operator identity:
    $ dfx upgrade
    $ dfx identity import node_operator node_operator_private_key.pem --storage-mode=plaintext
    
  2. Set IPv4 variables:
    $ NODE_ID="xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxx"
    # example: NODE_ID="pqjny-likm7-sjqik-x5m6r-doehn-djdf4-siihl-pnloo-gh3tb-ox6dy-dae"
    
    $ IPV4_PREFIX_LENGTH="xx"
    # example: IPV4_PREFIX_LENGTH="24"
    
    $ IPV4_ADDRESS="xxx.xxx.xxx.xxx"
    # example: IPV4_ADDRESS="12.15.1.89"
    
    $ IPV4_GATEWAY="gateway_ip"
    # example: IPV4_GATEWAY="12.15.1.1"
    
    $ DOMAIN="xxx.xxx.xxx"
    # example: DOMAIN="node1.example.com"
    
  3. Submit IPv4 dfx commands to add/update IPv4 configuration and domain name:
    // to add/update your IPv4 configuration:
    $ dfx canister --network ic --identity node_operator call rwlgt-iiaaa-aaaaa-aaaaa-cai update_node_ipv4_config_directly "(record { gateway_ip_addrs = vec {\"$IPV4_GATEWAY\"}; prefix_length = $IPV4_PREFIX_LENGTH : nat32; ip_addr = \"$IPV4_ADDRESS\"; node_id = principal \"$NODE_ID\" })"
    
    
    //  to add/update your domain name:
    

$ dfx canister --network ic --identity node_operator call rwlgt-iiaaa-aaaaa-aaaaa-cai update_node_domain_directly "(record { node_id = principal \"$NODE_ID\"; domain = opt \"$DOMAIN\" })" </syntaxhighlight>

    1. Dfx command to remove your node’s IPv4 configuration and domain name:
      // to remove your IPv4 configuration:
      $ dfx canister --network ic --identity node_operator call rwlgt-iiaaa-aaaaa-aaaaa-cai update_node_ipv4_config_directly '(record { ipv4_config = null; node_id = principal \"$NODE_ID\" })'
      

// to remove your domain name: $ dfx canister --network ic --identity node_operator call rwlgt-iiaaa-aaaaa-aaaaa-cai update_node_domain_directly '(record { node_id = principal \"$NODE_ID\"; domain = null })' </syntaxhighlight>
