## Network Attributes
These attributes may be used for any network related operation.
| Attribute | Type | Description | Examples | Stability |
| ---------------------------- | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------- | ---------------------------------------------------------------- |
| `network.carrier.icc` | string | The ISO 3166-1 alpha-2 2-character country code associated with the mobile carrier network. | `DE` |  |
| `network.carrier.mcc` | string | The mobile carrier country code. | `310` |  |
| `network.carrier.mnc` | string | The mobile carrier network code. | `001` |  |
| `network.carrier.name` | string | The name of the mobile carrier. | `sprint` |  |
| `network.connection.subtype` | string | This describes more details regarding the connection.type. It may be the type of cell technology connection, but it could be used for describing details about a wifi connection. | `gprs`; `edge`; `umts` |  |
| `network.connection.type` | string | The internet connection type. | `wifi`; `wired`; `cell` |  |
| `network.io.direction` | string | The network IO operation direction. | `transmit`; `receive` |  |
| `network.local.address` | string | Local address of the network connection - IP address or Unix domain socket name. | `10.1.2.80`; `/tmp/my.sock` |  |
| `network.local.port` | int | Local port number of the network connection. | `65123` |  |
| `network.peer.address` | string | Peer address of the network connection - IP address or Unix domain socket name. | `10.1.2.80`; `/tmp/my.sock` |  |
| `network.peer.port` | int | Peer port number of the network connection. | `65123` |  |
| `network.protocol.name` | string | [OSI application layer](https://osi-model.com/application-layer/) or non-OSI equivalent. [1] | `amqp`; `http`; `mqtt` |  |
| `network.protocol.version` | string | The actual version of the protocol used for network communication. [2] | `1.1`; `2` |  |
| `network.transport` | string | [OSI transport layer](https://osi-model.com/transport-layer/) or [inter-process communication method](https://wikipedia.org/wiki/Inter-process_communication). [3] | `tcp`; `udp`; `pipe` |  |
| `network.type` | string | [OSI network layer](https://osi-model.com/network-layer/) or non-OSI equivalent. [4] | `ipv4`; `ipv6` |  |
**[1]:** The value SHOULD be normalized to lowercase.
**[2]:** If protocol version is subject to negotiation (for example using [ALPN](https://www.rfc-editor.org/rfc/rfc7301.html)), this attribute SHOULD be set to the negotiated version. If the actual protocol version is not known, this attribute SHOULD NOT be set.
**[3]:** The value SHOULD be normalized to lowercase.
Consider always setting the transport when setting a port number, since
a port number is ambiguous without knowing the transport. For example
different processes could be listening on TCP port 12345 and UDP port 12345.
**[4]:** The value SHOULD be normalized to lowercase.
