Network Attributes

These attributes may be used for any network related operation.

Attributes:

Key	Stability	Value Type	Description	Example Values
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.state		string	The state of network connection [1]	close_wait
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.	LTE
network.connection.type		string	The internet connection type.	wifi
network.interface.name		string	The network interface name.	lo; eth0
network.io.direction		string	The network IO operation direction.	transmit
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 or non-OSI equivalent. [2]	amqp; http; mqtt
network.protocol.version		string	The actual version of the protocol used for network communication. [3]	1.1; 2
network.transport		string	OSI transport layer or inter-process communication method. [4]	tcp; udp
network.type		string	OSI network layer or non-OSI equivalent. [5]	ipv4; ipv6

[1] network.connection.state: Connection states are defined as part of the rfc9293

[2] network.protocol.name: The value SHOULD be normalized to lowercase.

[3] network.protocol.version: If protocol version is subject to negotiation (for example using ALPN), this attribute SHOULD be set to the negotiated version. If the actual protocol version is not known, this attribute SHOULD NOT be set.

[4] network.transport: 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.

[5] network.type: The value SHOULD be normalized to lowercase.

network.connection.state has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.
