45 # Captures a socket address or address range in the Internet

47 #
48 # @numeric: true if the host/port are guaranteed to be numeric, false
49 # if name resolution should be attempted. Defaults to false.
50 # (Since 2.9)

55 # @ipv4: whether to accept IPv4 addresses, default try both IPv4 and
56 # IPv6

67 # where TCP_KEEPCNT socket option is defined (this includes Linux,

69 # system setting is used. (Since 10.1)

71 # @keep-alive-idle: time in seconds the connection needs to be idle
72 # before sending a keepalive packet. Only supported for TCP
73 # sockets on systems where TCP_KEEPIDLE socket option is defined
74 # (this includes Linux, Windows, macOS, FreeBSD, but not OpenBSD).
75 # When set to 0, system setting is used. (Since 10.1)
