# URL Format

Some commands (e.g., [write network](/island-router-cli-2.3.2/commands/write/write-network.md)) require a URL argument to identify a remote file or directory. The format for a URL argument is:

`scheme://[username[:password]@]host[:port]/[path]`

Supported schemes for most commands are http, https, ftp, ftps, sftp, scp, smb, and tftp.

The host parameter may be an IP address or a domain name.

The optional port parameter is not supported on all protocols.
