[FUG-BR] conflito de IP na rede

[Edinilson - ATINET]

Instale o arping:
/usr/ports/net/arping

Depois disto:
arping -i dc0 10.10.4.117

Veja QUAL mac exatamente é retornado.

As vezes algum cliente muda o IP ou entao, SE o radio estiver em modo 
BRIDGE, pode ser que ele tenha ligado o radio diretamente no switch dele.

Sobre o 169.254.11.248, é o IP de micros com OS Microsoft quando nao 
conseguem pegar um IP com algum servidor DHCP.
Voce tambem pode usar o arping contra este IP e ver qual cliente é.
