==========================
Delphi IPHelper functions
==========================
Required OS : NT4/SP4 or higher, WIN98/WIN98se
Developed on: D6 Ent. & Prof.
Tested on : WIN-NT4/SP6, WIN98se, WIN95/OSR1
: WIN98, W2K-SP2, 3, 4
: W2K, W2K prof, W2K server
Warning - currently only supports Delphi 5 and later unless int64 is removed
(Int64 is only used to force Format to show unsigned 32-bit numbers)
================================================================
This software is FREEWARE
-------------------------
If this software works, it was surely written by Dirk Claessens

(If it doesn't, I don't know anything about it.)
================================================================
{ List of Fixes & Additions
v1.1 dirkcl
-----
Fix : wrong errorcode reported in GetNetworkParams()
Fix : RTTI MaxHops 20 > 128
Add : ICMP -statistics
Add : Well-Known port numbers
Add : RecentIP list
Add : Timer update
v1.2 dirkcl
----
Fix : Recent IP's correct update
ADD : ICMP-error codes translated
v1.3 - 18th September 2001
----
Angus Robertson, Magenta Systems Ltd, England
[email protected], http://www.magsys.co.uk/delphi/
Slowly converting procs into functions that can be used by other programs,
ie Get_ becomes IpHlp
Primary improvements are that current DNS server is now shown, also
in/out bytes for each interface (aka adaptor)
All functions are dynamically loaded so program can be used on W95/NT4
Tested with Delphi 6 on Windows 2000 and XP
v1.4 - 28th February 2002 - Angus
----
Fixed major memory leak in IpHlpIfTable (except instead of finally)
Fixed major memory leak in Get_AdaptersInfo (incremented buffer pointer)
Created IpHlpAdaptersInfo which returns TAdaptorRows
Note: IpHlpNetworkParams returns dynamic DNS address (and other stuff)
Note: IpHlpIfEntry returns bytes in/out for a network adaptor
v1.5 - 5th October 2003
