# Network Configuration Settings [Receivers](https://github.com/open-telemetry/opentelemetry-collector/blob/main/receiver/README.md) leverage network configuration to set connection and transport information. - `endpoint`: Configures the address for this network connection. For TCP and UDP networks, the address has the form "host:port". The host must be a literal IP address, or a host name that can be resolved to IP addresses. The port must be a literal port number or a service name. If the host is a literal IPv6 address it must be enclosed in square brackets, as in "[2001:db8::1]:80" or "[fe80::1%zone]:80". The zone specifies the scope of the literal IPv6 address as defined in RFC 4007. - `transport`: Known protocols are "tcp", "tcp4" (IPv4-only), "tcp6" (IPv6-only), "udp", "udp4" (IPv4-only), "udp6" (IPv6-only), "ip", "ip4" (IPv4-only), "ip6" (IPv6-only), "unix", "unixgram" and "unixpacket". Note that for TCP receivers only the `endpoint` configuration setting is required.
