# tcp(), tcp6(), udp() and udp6() source options: OBSOLETE

> **Note:**
> The `tcp()`, `tcp6()`, `udp()`, and `udp6()` drivers are obsolete. Use the `network()` source and the `network()` destination instead. For details, see [network: Collect messages using the RFC3164 protocol (network() driver)](https://axoflow.com/docs/axosyslog-core/4.28/chapter-sources/configuring-sources-network/index.md) and [network: Send messages to a remote log server using the RFC3164 protocol (network() driver)](https://axoflow.com/docs/axosyslog-core/4.28/chapter-destinations/configuring-destinations-network/index.md), respectively.

To convert your existing `tcp()`, `tcp6()`, `udp()`, `udp6()` source drivers to use the `network()` driver, see [Change an old source driver to the network() driver](https://axoflow.com/docs/axosyslog-core/4.28/chapter-sources/configuring-sources-tcpudp/reference-source-tcpudp/source-tcpudp-to-network/index.md).
