Assigning Broadcast as a DNS address

Hey Guys,

Sorry if I should not be posting this here. Just a query (my networking skills are very rusty). A work collegue of mine was tasked with updating the address of the DNS servers. He accidently put 255 of the 4th octet of the IP address instead of 225.

I made him change them all there and then. However i was told by other collegues that I was over reacting and it could of waited.

What effect would this of had on a Production network, if 50 servers were using a broadcast address to resolve dns queries?

For clarification, its the DNS server setting when you configure IPv4 in Windows.
