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.	LTE
network.connection.type	string	The internet connection type.	wifi
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. [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 or inter-process communication method. [3]	tcp; udp
network.type	string	OSI 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), 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.
