I am working on a DHCP Subnet for my company and I went to change ip
address for the Domain Name Service (Option 6) under Other DHCP Options and
go to save it I get:

The Value in this field is out of range. The value range is 0 through 365.
Reenter a value.

I have all the values correct and I am not using any numbers beyond 254.

Any ideas what could be causing this?
