This would only affect reverse lookups. But all major routers should be 
configured not to route that subnet, so you won't get very far. Someone 
trying to fool your computer into thinking 169.254.10.5 is something 
important, like your bank, would have to be local to you (as in one hop away) 
in order to gain any advantage from it.

But if someone has high level access to your local LAN, there are far easier 
ways to trick your computer that doesn't involve cracking IANA's name servers
