Get Global IP address

[Phantomas]

Hi, this is a simple procedure for get your global IP address.
Working with checkip.dyndns.org WEB server.

ProcedureReturn not used. Errors are handled in end of procedure (result = *).

Edit:
Thank to ts-soft for constant #PB_Ascii in PeekS().

[ts-soft]

Small problem, doesn't work with unicode!
Change line 68 to:

Code: Select all

              string_to_send_current_ip = PeekS(*memory_global, -1, #PB_Ascii)

and it works.

ts-soft, thanks! Updated...

Curious why you didn't use a simple GetHTTPHeader()?
Is it because no error checking?

Code: Select all

Procedure.s NL_ExtIP()
  Protected.s ExtIP$
  Protected.i Lpos, Rpos
  ExtIP$ = GetHTTPHeader("http://checkip.dyndns.org/")
  Lpos = FindString(ExtIP$, "IP Address:") + 11
  Rpos = FindString(ExtIP$, "<", Lpos) + 1
  ExtIP$ = Trim(Mid(ExtIP$, Lpos, Len(ExtIP$) - Rpos))
  ProcedureReturn ExtIP$
EndProcedure

;Debug GetHTTPHeader("http://checkip.dyndns.org/")
InitNetwork()
Debug NL_ExtIP()

Hardly suitable for something where the IP is needed by the program for it to operate lol.

Nice code, Phantomas Thanks for sharing

Wow, this server (dyndns.org) always responds the current IP to any query. This is not correct on the server side (but comfortably). I did not know it. Because of what used GET (HTTP standard).
And yes, no timeout option, errors checking, etc.

Yes! Excellent!

If you're connected directly to the modem device you can also use PnP to get it, if ony a sub device you have to use a service though. A simple HTTP get with TCP works fine, just disable compression and check for chunking.

Or you could do what i've been using, for public IPv4 or IPv6 address.

The PureBasic versions:

Code: Select all

Procedure.s GetPubIPv4Address()
  ; https://www.ipify.org/
  InitNetwork()
  *Buffer = ReceiveHTTPMemory("https://api.ipify.org?format=json")
  If *Buffer
    ParseJSON(0, PeekS(*Buffer, MemorySize(*Buffer), #PB_UTF8))
    FreeMemory(*Buffer)
    ip4addrs$ = GetJSONString(GetJSONMember(JSONValue(0), "ip"))
  EndIf
  
  ProcedureReturn Trim(ip4addrs$)
  
EndProcedure

Procedure.s GetPubIPv6Address()
  ; http://ip6.anysrc.net/json
  InitNetwork()
  *Buffer = ReceiveHTTPMemory("http://ip6.anysrc.net/json")
  If *Buffer
    ParseJSON(0, PeekS(*Buffer, MemorySize(*Buffer), #PB_UTF8))
    FreeMemory(*Buffer)
    ip6addrs$ = GetJSONString(GetJSONMember(JSONValue(0), "clientip"))
  EndIf
  
  ProcedureReturn Trim(ip6addrs$)
  
EndProcedure

Debug GetPubIPv4Address()
Debug GetPubIPv6Address()

The code above is from the http://www.ipify.org site and written by the owner of that site (I think, he has contributors also, so one of them may have written it - scroll down a little on his page and he has implementations for different coding platforms), credit to him. I used the same code for the IPv6 side also and just changed the site address. You can just about plug in any site that uses json.

smacker...
Seems like lots of good stuff in there, but I can't find procedure GetValidateIPAddress()

location - inside procedure: GetIPv4AddressPublic()

@blueb,

sorry 'bout that, got left out of the copy-n-paste to the post - the GetValidateIPAddress() procedure is:

Code: Select all

Procedure.b GetValidateIPAddress(ipadrtoval$) 
  ; will validate IPv4 and IPv6
  ipadr$ = Chr(34) + Chr(39) + ipadrtoval$ + Chr(39) + Chr(34)
  
  OutCmd$ = ""
  KeepOutCmdA$ = ""
  CmdPromptRun = RunProgram("powershell.exe", " [System.Net.IPAddress]::TryParse( " + ipadr$ + ", [ref] $NULL)","", #PB_Program_Hide|#PB_Program_Open|#PB_Program_Read)
  If CmdPromptRun
    While ProgramRunning(CmdPromptRun)
      OutCmd$=ReadProgramString(CmdPromptRun)
      KeepOutCmdA$ = KeepOutCmdA$ + OutCmd$
    Wend
    CloseProgram(CmdPromptRun)
  EndIf
  
  If Trim(KeepOutCmdA$) = "True"
    ProcedureReturn #True ; is a valid IPv4 or IPv6 address
  Else
    ProcedureReturn #False  ; is not a valid IPv4 or IPv6 address
  EndIf
  
EndProcedure

I also updated the other post to include it.

Note that TryParse returns true if it parsed the input successfully but that this does not necessarily mean the IP address fed to it is a valid IP address for use. Used for error trapping above, for example, if the sites API hiccups and returns nothing for the IP or returns an API error message of some sort, etc... so we move on to another site, because the site can be up and functioning but the API used to return the IP address could be experiencing an issue. For an IP address its basically determining whether or not the input string, e.g. 0.0.0.0, string can be converted to a valid IP address so its possible to have a non-usable IP address, e.g. 0.0.0.0, and TryParse will return true because it can convert the input to a valid IP address even if the IP is not one which is usable for networking or on the internet because, using the example 0.0.0.0, an address of 0.0.0.0 is still a valid IP address format wise. Works for IPv4 and IPv6, not perfect, but widely used and a lot simpler and easier than messing around with a regex, and its kinda fun being able to use a little .net in purebasic.
