ddwrt DNS resolution error due to question mark

Just an FYI to anyone who mistakenly puts a question mark (i.e. ?) at the end of one of their hostnames in the static leases section of their DHCP server tab. It will hose all DNS lookups (i.e. no internet) on the network served by the ddwrt router. I know this should be obvious to any web developer, but I did this and it took me 30 mins to resolve the issue. Hope this helps someone else.
