Por que meu nome de host resolve o IP do nic virtual e não o físico?

0

Eu tenho o Virtual Box instalado no meu computador com Windows 8 e, como tal, tenho alguns adaptadores de rede virtual

Meu problema é que quando eu faço ping sedtdev1510 ou programaticamente resolvo o IP, a partir do computador local, o IP de um dos adaptadores de rede virtual é retornado em vez do IP do adaptador físico.

Exemplo:

ping -4 sedtdev1510

Pinging SEDTDEV1510.euse.local [192.168.56.1] with 32 bytes of data:
Reply from 192.168.56.1: bytes=32 time<1ms TTL=128

O IP esperado é 172.16.5.126

  • Não há entradas no meu arquivo "C: \ Windows \ System32 \ drivers \ etc \ hosts".
  • Meu adaptador de rede física é o primeiro da lista de "conexões" em "Configurações avançadas" para Conexões de rede.
  • Se eu desativar os adaptadores virtuais, o IP correto será retornado (não uma solução de longo prazo).
  • Se eu pingar meu nome de host de outro computador da rede 172.16.5, o IP correto será resolvido, portanto, isso é um problema local.

O DNS parece estar OK, pois o nslookup retorna o IP correto:

nslookup sedtdev1510
Server:  ad01.euse.local
Address:  172.16.1.1

Name:    sedtdev1510.euse.local
Address:  172.16.5.126

Então, minha pergunta é: por que o Windows se comporta dessa maneira e o que eu preciso fazer para que meu nome de host resolva localmente para o IP do adaptador físico?

Esta é a saída do ipconfig / all
