default dhcp - If checked, this scope will be used for clients when their network can't be determined. #1077

Hi,

so I have multiple scope configured handing out IPs without issues (all via relay).

I enabled the "If checked, this scope will be used for clients when their network can't be determined." on one of my scope. All of a sudden dhcp client that had IP addresses from their respective scope started getting IPs from the "default" enabled scope instead.. turning it off returned things to normal

hmm, yeah the intended functionality of this is that "as a last resort", if scope can't be detected via network/relay then the scope with this flag enabled should be used, it shouldn't affect correct matches to other scopes

what are the criteria for a scope to be detected via network/relay? all my configured subnet / scope are using the same relay server that throws the request to gravity.
