+.Sh NAME
+.Nm getaddrinfo
+.Nd resolve names to socket addresses
+.Sh SYNOPSIS
+.Nm
+.Op Fl cNnP
+.Op Fl f Ar family
+.Op Fl p Ar protocol
+.Op Fl s Ar service Ns Op Ns / Ns Ar protocol
+.Op Fl t Ar socktype
+.Op Ar hostname
+.Sh DESCRIPTION
+The
+.Nm
+utility resolves host and service names to socket addresses with
+.Xr getaddrinfo 3
+and prints them to standard output in a user-friendly format.
+.Pp
+The output is a sequence of lines with space-separated fields:
+.Pp
+.Dl socket-type address-family protocol [af-specific data ...]
+.Pp
+For the
+.Dq inet
+and
+.Dq inet6
+address families, the af-specific data are the IP/IPv6 address and port
+number.
+.Pp
+Depending on the settings in
+.Xr nsswitch.conf 5 ,
+.Nm
+might query DNS for answers.
+However, it is not intended to be a general-purpose DNS query utility.
+Use
+.Xr drill 1
+for that.
+.Pp
+These options are available:
+.Bl -tag -width Ds
+.It Fl c
+Look up a canonical name as if with the
+.Dv AI_CANONNAME
+flag to
+.Xr getaddrinfo 3
+and print it on the first line before the socket addresses.
+.It Fl f Ar family
+Specify an address family.
+Address families are named like the
+.Dv AF_...
+constants for address family numbers in the
+.Aq Pa sys/socket.h
+header file but without the
+.Dv AF_
+prefix and lowercase.
+For example,
+.Dq inet
+corresponds with
+.Dv AF_INET .
+.It Fl N
+Treat the service as numeric and do not attempt service name
+resolution, as if with the
+.Dv AI_NUMERICSERV
+flag to
+.Xr getaddrinfo 3 .
+.It Fl n
+Treat the hostname as a numeric address and do not attempt name
+resolution, as if with the
+.Dv AI_NUMERICHOST
+flag to
+.Xr getaddrinfo 3 .
+.It Fl P
+Return socket addresses intended for use with
+.Xr bind 2 ,
+as if with the
+.Dv AI_PASSIVE
+flag to
+.Xr getaddrinfo 3 .
+By default, the socket addresses are intended for use with
+.Xr connect 2 ,
+.Xr sendto 2 ,
+or
+.Xr sendmsg 2 .
+.It Fl p Ar protocol
+Specify a protocol.
+Protocols are numeric or symbolic as listed in
+.Xr protocols 5 .
+.It Fl s Ar service Ns Op Ns / Ns Ar protocol
+Specify a service to look up.
+Services are symbolic or numeric with an optional
+protocol suffix as listed in
+.Xr services 5 .
+If a service is not specified, a hostname is required.
+.It Fl t Ar socktype
+Specify a socket type.
+Socket types are named like the
+.Dv SOCK_...
+constants for socket type numbers in the
+.Aq Pa sys/socket.h
+header file but without the
+.Dv SOCK_
+prefix and lowercase.
+For example,
+.Dq dgram
+corresponds with
+.Dv SOCK_DGRAM .
+.El
+.Sh EXIT STATUS
+.Ex -std getaddrinfo
+.Sh EXAMPLES
+Look up
+.Dq www.NetBSD.org :
+.Bd -literal -offset indent
+$ getaddrinfo www.NetBSD.org
+dgram inet6 udp 2001:4f8:3:7:2e0:81ff:fe52:9ab6 0
+dgram inet udp 149.20.53.67 0
+stream inet6 tcp 2001:4f8:3:7:2e0:81ff:fe52:9ab6 0
+stream inet tcp 149.20.53.67 0
+.Ed
+.Pp
+The port number here is zero because no service was specified.
+.Pp
+Look up
+.Dq morden.NetBSD.org
+for stream sockets on port 80, and show the canonical name:
+.Bd -literal -offset indent
+$ getaddrinfo -c -t stream -s 80 morden.NetBSD.org
+canonname ftp.NetBSD.org
+stream inet6 tcp 2001:470:1f05:3d::21 80
+stream inet tcp 199.233.217.249 80
