mostrar ip local

[Kizar]

Y sin usar el control winsock como podria conocer mi ip, es k con las apis estuve mirando y son codes muy largos para algo tan sencillo....

haber, en tu lan (tu red logica y fisica) tienes una ip, que suele ser 192.168.0.x el router tiene 192.168.0.1 pero si alguien desde internet se quiere conectar a tu ordenador a de saber la ip externa, la que utilizas de cara a internet, como puedo averiguar esa ip? supongo que el winsock no puede averiguarla ya que esta en el router que es como otro ordenador, por tanto tendria que preguntarsela al router, pero no se como

[#Borracho.-]

Pero para eso ya tendría que haber un programa en tu pc y otro en el router... O si no si está conectado con vos... Con shell que se fije el netstat y te diga la ip del router que vos queres saber.

No es asi?

Pues utiliza el emulador, socketmaster o algo asi verdad?
Busca info en el foro

[{_The_Alwar_}]

nose, digo yo q se le podra enviar algun comando al router y que te devuelva datos, en linux seria facil, haces un traceroute y con el grep cojes la segunda ip, en windows no se como pueda filtrar la salida estandar que de tracert

ya usaba el socketmaster peor este pones ws.localIP y no te muestra nada

 no puedes conocer la ip publica de tu red desde el winsock u otra clase que emule a este control por medio del .localip, tendrias que usar el winsock, y conectarte a una pagina  de esas que te dicen la ip, osea todo por medio de http, capturas los priemros datos que te mandan,.. me explico,..

por ejemplo en la pagina http://whatsmyip.org/ te da tu ip publica, lo que tendrias que hacer es conectarte a esta page y buscar entre el code html las palabras "Your IP Address is" y luego sacar la infoq ue sigue, que seria tu ip,.. me explique? :p

y bue, pa sacar la ip local sin el winsock puedes usar este code que encontre hace mucho,...

que como puedes ver hay dos funciones que rtetornan la ip local y el nombre del host local o nombre de red

[#Borracho.-]

son codes muy largos para algo tan sencillo....

Si, es muy largo el code aunque es una buena opción y funcional. Alguien sabe de otra mas corta y funcional?

Insserta un label, un command y un winsock
en el command codifica asì:
private sub command1_click()
label1=winsock1.localip
end sub

solamente, espero que te funcione
