## Source Attributes
|
|
|
|
These attributes may be used to describe the sender of a network exchange/packet. These should be used when there is no client/server relationship between the two sides, or when that relationship is unknown. This covers low-level network interactions (e.g. packet tracing) where you don't know if there was a connection or which side initiated it. This also covers unidirectional UDP flows and peer-to-peer communication where the "user-facing" surface of the protocol / API doesn't expose a clear notion of client and server.

|
| Attribute | Type | Description | Examples | Stability |
|
|
|---|---|---|---|---|
|
|
| <a id="source-address" href="#source-address">`source.address`</a> | string | Source address - domain name if available without reverse DNS lookup; otherwise, IP address or Unix domain socket name. [1] | `source.example.com`; `10.1.2.80`; `/tmp/my.sock` |  |
|
|
| <a id="source-port" href="#source-port">`source.port`</a> | int | Source port number | `3389`; `2888` |  |
|
|
|
|
**[1] `source.address`:** When observed from the destination side, and when communicating through an intermediary, `source.address` SHOULD represent the source address behind any intermediaries, for example proxies, if it's available.
