+.Sh DESCRIPTION
+.Fn getipnodebyname
+and
+.Fn getipnodebyaddr
+functions are very similar to
+.Xr gethostbyname 3 ,
+.Xr gethostbyname2 3
+and
+.Xr gethostbyaddr 3 .
+The functions cover all the functionalities provided by the older ones,
+and provide better interface to programmers.
+The functions require additional arguments,
+.Ar af ,
+and
+.Ar flags ,
+for specifying address family and operation mode.
+The additional arguments allow programmer to get address for a nodename,
+for specific address family
+(such as
+.Dv AF_INET
+or
+.Dv AF_INET6 ) .
+The functions also require an additional pointer argument,
+.Ar error_num
+to return the appropriate error code,
+to support thread safe error code returns.
+.Pp
+The type and usage of the return value,
+.Li "struct hostent"
+is described in
+.Xr gethostbyname 3 .
+.Pp
+For
+.Fn getipnodebyname ,
+the
+.Ar name
+argument can be either a node name or a numeric address
+string
+(i.e., a dotted-decimal IPv4 address or an IPv6 hex address).
+The
+.Ar af
+argument specifies the address family, either
+.Dv AF_INET
+or
+.Dv AF_INET6 .
+The
+.Ar flags
+argument specifies the types of addresses that are searched for,
+and the types of addresses that are returned.
+We note that a special flags value of
+.Dv AI_DEFAULT
+(defined below)
+should handle most applications.
+That is, porting simple applications to use IPv6 replaces the call
+.Bd -literal -offset
+   hptr = gethostbyname(name);
+.Ed
+.Pp
+with
+.Bd -literal -offset
+   hptr = getipnodebyname(name, AF_INET6, AI_DEFAULT, &error_num);
+.Ed
+.Pp
+Applications desiring finer control over the types of addresses
+searched for and returned, can specify other combinations of the
+.Ar flags
+argument.
+.Pp
+A
+.Ar flags
+of
+.Li 0
+implies a strict interpretation of the
+.Ar af
+argument:
+.Bl -bullet
+.It
+If
+.Ar flags
+is 0 and
+.Ar af
+is
+.Dv AF_INET ,
+then the caller wants only IPv4 addresses.
+A query is made for
+.Li A
+records.
+If successful, the IPv4 addresses are returned and the
+.Li h_length
+member of the
+.Li hostent
+structure will be 4, else the function returns a
+.Dv NULL
+pointer.
+.It
+If
+.Ar flags
+is 0 and if
+.Ar af
+is
+.Li AF_INET6 ,
+then the caller wants only IPv6 addresses.
+A query is made for
+.Li AAAA
+records.
+If successful, the IPv6 addresses are returned and the
+.Li h_length
+member of the
+.Li hostent
+structure will be 16, else the function returns a
+.Dv NULL
+pointer.
+.El
+.Pp
+Other constants can be logically-ORed into the
+.Ar flags
+argument, to modify the behavior of the function.
+.Bl -bullet
+.It
+If the
+.Dv AI_V4MAPPED
+flag is specified along with an
+.Ar af
+of
+.Dv AF_INET6 ,
+then the caller will accept IPv4-mapped IPv6 addresses.
+That is, if no
+.Li AAAA
+records are found then a query is made for
+.Li A
+records and any found are returned as IPv4-mapped IPv6 addresses
+.Li ( h_length
+will be 16).
+The
+.Dv AI_V4MAPPED
+flag is ignored unless
+.Ar af
+equals
+.Dv AF_INET6 .
+.It
+The
+.Dv AI_V4MAPPED_CFG
+flag is exact same as the
+.Dv AI_V4MAPPED
+flag only if the kernel supports IPv4-mapped IPv6 address.
+.It
+If the
+.Dv AI_ALL
+flag is used in conjunction with the
+.Dv AI_V4MAPPED
+flag, and only used with the IPv6 address family.
+When
+.Dv AI_ALL
+is logically or'd with
+.Dv AI_V4MAPPED
+flag then the caller wants all addresses: IPv6 and IPv4-mapped IPv6.
+A query is first made for
+.Li AAAA
+records and if successful, the
+IPv6 addresses are returned.  Another query is then made for
+.Li A
+records and any found are returned as IPv4-mapped IPv6 addresses.
+.Li h_length
+will be 16.  Only if both queries fail does the function
+return a
+.Dv NULL
+pointer.  This flag is ignored unless af equals
+AF_INET6.  If both
+.Dv AI_ALL
+and
+.Dv AI_V4MAPPED
+are specified,
+.Dv AI_ALL
+takes precedence.
+.It
+The
+.Dv AI_ADDRCONFIG
+flag specifies that a query for
+.Li AAAA
+records
+should occur only if the node has at least one IPv6 source
+address configured and a query for
+.Li A
+records should occur only if the node has at least one IPv4 source address
+configured.
+.Pp
+For example, if the node has no IPv6 source addresses configured,
+and
+.Ar af
+equals AF_INET6, and the node name being looked up has both
+.Li AAAA
+and
+.Li A
+records, then:
+(a) if only
+.Dv AI_ADDRCONFIG
+is
+specified, the function returns a
+.Dv NULL
+pointer;
+(b) if
+.Dv AI_ADDRCONFIG
+|
+.Dv AI_V4MAPPED
+is specified, the
+.Li A
+records are returned as IPv4-mapped IPv6 addresses;
+.El
+.Pp
+The special flags value of
+.Dv AI_DEFAULT
+is defined as
+.Bd -literal -offset
+   #define  AI_DEFAULT  (AI_V4MAPPED_CFG | AI_ADDRCONFIG)
+.Ed
+.Pp
+We noted that the
+.Fn getipnodebyname
+function must allow the
+.Ar name
+argument to be either a node name or a literal address string
+(i.e., a dotted-decimal IPv4 address or an IPv6 hex address).
+This saves applications from having to call
+.Xr inet_pton 3
+to handle literal address strings.
+When the
+.Ar name
+argument is a literal address string,
+the
+.Ar flags
+argument is always ignored.
+.Pp
+There are four scenarios based on the type of literal address string
+and the value of the
+.Ar af
+argument.
+The two simple cases are when
+.Ar name
+is a dotted-decimal IPv4 address and
+.Ar af
+equals
+.Dv AF_INET ,
+or when
+.Ar name
+is an IPv6 hex address and
+.Ar af
+equals
+.Dv AF_INET6 .
+The members of the
+returned hostent structure are:
+.Li h_name
+points to a copy of the
+.Ar name
+argument,
+.Li h_aliases
+is a
+.Dv NULL
+pointer,
+.Li h_addrtype
+is a copy of the
+.Ar af
+argument,
+.Li h_length
+is either 4
+(for
+.Dv AF_INET )
+or 16
+(for
+.Dv AF_INET6 ) ,
+.Li h_addr_list[0]
+is a pointer to the 4-byte or 16-byte binary address,
+and
+.Li h_addr_list[1]
+is a
+.Dv NULL
+pointer.
+.Pp
+When
+.Ar name
+is a dotted-decimal IPv4 address and
+.Ar af
+equals
+.Dv AF_INET6 ,
+and
+.Dv AI_V4MAPPED
+is specified,
+an IPv4-mapped IPv6 address is returned:
+.Li h_name
+points to an IPv6 hex address containing the IPv4-mapped IPv6 address,
+.Li h_aliases
+is a
+.Dv NULL
+pointer,
+.Li h_addrtype
+is
+.Dv AF_INET6 ,
+.Li h_length
+is 16,
+.Li h_addr_list[0]
+is a pointer to the 16-byte binary address, and
+.Li h_addr_list[1]
+is a
+.Dv NULL
+pointer.
+.Pp
+It is an error when
+.Ar name
+is an IPv6 hex address and
+.Ar af
+equals
+.Dv AF_INET .
+The function's return value is a
+.Dv NULL
+pointer and the value pointed to by
+.Ar error_num
+equals
+.Dv HOST_NOT_FOUND .
+.Pp
+.Fn getipnodebyaddr
+takes almost the same argument as
+.Xr gethostbyaddr 3 ,
+but adds a pointer to return an error number.
+Additionally it takes care of IPv4-mapped IPv6 addresses,
+and IPv4-compatible IPv6 addresses.
+.Pp
+.Fn getipnodebyname
+and
+.Fn getipnodebyaddr
+dynamically allocate the structure to be returned to the caller.
+.Fn freehostent
+reclaims memory region allocated and returned by
+.Fn getipnodebyname
+or
+.Fn getipnodebyaddr .

+.Sh HISTORY
+The implementation first appeared in KAME advanced networking kit.
+.\"
+.Sh STANDARDS
+.Fn getipnodebyname
+and
+.Fn getipnodebyaddr
+are documented in
+.Dq Basic Socket Interface Extensions for IPv6
+(RFC2553).
+.\"
+.Sh BUGS
+.Fn getipnodebyname
+and
+.Fn getipnodebyaddr
+do not handle scoped IPv6 address properly.
+If you use these functions,
+your program will not be able to handle scoped IPv6 addresses.
+For IPv6 address manipulation,
+.Fn getaddrinfo 3
+and
+.Fn getnameinfo 3
+are recommended.
+.Pp
+The current implementation is not thread-safe.
+.Pp
+The text was shamelessly copied from RFC2553.
