Get MAC Address and IP number
Hi, All of us know how to get the MAC Address and IP number using Windows functions, because we have a lot of examples on internet. But now in Mac platform, how we can get this information too? Thanks in advance.

Try this:
{code}
program Project1;
{$APPTYPE CONSOLE}
{$R *.res}
uses
System.SysUtils,
Posix.Base,
Posix.SysSocket,
Posix.NetIf,
Posix.NetinetIn,
Posix.ArpaInet;
type
u_char = UInt8;
u_short = UInt16;
sockaddr_dl = record
sdl_len: u_char; //* Total length of sockaddr */
sdl_family: u_char; //* AF_LINK */
sdl_index: u_short; //* if != 0, system given index for interface */
sdl_type: u_char; //* interface type */
sdl_nlen: u_char; //* interface name length, no trailing 0 reqd. */
sdl_alen: u_char; //* link level address length */
sdl_slen: u_char; //* link layer selector length */
sdl_data: array[0..11] of AnsiChar; //* minimum work area, can be larger;
//contains both if name and ll address */
end;
psockaddr_dl = ^sockaddr_dl;
const
IFT_ETHER = $6; //if_types.h
function getifaddrs(var ifap: pifaddrs): Integer; cdecl;
external libc name _PU + 'getifaddrs';
{$EXTERNALSYM getifaddrs}
procedure freeifaddrs(ifp: pifaddrs); cdecl;
external libc name _PU + 'freeifaddrs';
{$EXTERNALSYM freeifaddrs}
var
ifap, Next: pifaddrs;
sdp : psockaddr_dl;
MacAddr : array[0..5] of Byte;
cur: AnsiString;
ip: AnsiString;
begin
try
if getifaddrs(ifap) <> 0 then
RaiseLastOSError;
try
WriteLn('');
SetLength(ip, INET6_ADDRSTRLEN);
Next := ifap;
while Next <> nil do
begin
if cur <> AnsiString(Next.ifa_name) then
begin
cur := AnsiString(Next.ifa_name);
Write(cur);
WriteLn(': flags: ' + IntToHex(Next.ifa_flags, 4));
end;
case Next.ifa_addr.sa_family of
AF_LINK :
begin
sdp := psockaddr_dl(Next.ifa_addr);
if sdp.sdl_type = IFT_ETHER then
begin
Move(Pointer(PAnsiChar(@sdp^.sdl_data[0]) + sdp.sdl_nlen)^, MacAddr, 6);
WriteLn(Format(' ethernet ID: %x:%x:%x:%x:%x:%x',
[MacAddr[0], MacAddr[1], MacAddr[2], MacAddr[3], MacAddr[4], MacAddr[5]]));
end;
end;
AF_INET, AF_INET6:
begin
FillChar(Pointer(ip)^, INET6_ADDRSTRLEN, #0);
inet_ntop(Next.ifa_addr.sa_family, @psockaddr_in(Next.ifa_addr)^.sin_addr, PAnsiChar(IP), INET6_ADDRSTRLEN);
WriteLn(' IP: ' + ip);
end;
end;
Next := Next.ifa_next;
end;
finally
freeifaddrs(ifap);
end;
except
on E: Exception do
Writeln(E.ClassName, ': ', E.Message);
end;
end.
{code}

Well, inet_ntop() doesn't seem to well format IPv6 addresses.
Find a better routine, i.e. such as ICS' WSocketIPv6ToStr() from
its IPv6 branch: svn://svn.overbyte.be/ics/branches/icsipv6.
Both, username und password "ics".

IP address vs MAC address
Ok somebody explain this to me. I understand how IP addresses are issued(well sort of...lol) Is it one IP address to one MAC address?(not accounting for non routable IP space) I understand there can only be one WAN facing IP address per machine/MAC/NIC/etc realizing multiple NICs possible on one computer. If that is the case then how can say a Comcast DHCP server keep from issuing an IP to a MAC address that another provider has already issued an IP for? In this case perhaps someone has made up a MAC address to use in their router for cloning purposes. Or does it really ...

how to find ip address from mac address?
It happened more than once. At a customer's office, there is a device with an unknown ip address. We know its mac address. The ip address might be different from the network. For example, the customer's network might be 10.1.0.0/16, whereas that device might have the ip address 192.168.200.123/24. For example, it might be a managed switch that has kept its default ip address. So, it works as a switch, but I cannot manage it. Apart from a sniffer, is there a (free?) software that can scan the network and find ip addresses of all hosts, and/or only of those whose mac address ...

Yes. Just create an ip-address-object with manual assignment type in the DNS/DHCP management console.
