Det ser specielt ud.

arp fortæller dig at der er en maskine på dit lokalnetværk  med
macadressen 00:0F:23:E1:9E:70 der siger at den har ip-nummeret
72.14.221.91. 

Navnet fg-in-f91.google.com er bare et resultat af at slå ip-nummeret
op i DNS. Det kan være hvad som helst. Men hvorfor er der en af dine
lokalmaskiner der tror den har smamme ip-nummer som en af ggoogles
maskiner?

(Du er vel ikke på besøg hos google?)

Vil du fortælle os noget om din netværksopsætning? (arp er kun
relevant når man debugger netværk).
