I reproduce it typically by not having a network connection!

OK, so the solution is more complicated: NetNameResolver >>
#addressForName:timeout: must have a way of signalling not only a name
lookup failure (which loops via the exception's defaultAction) but
also a name lookup failure where the user gives up. Given the return
values, how about

    result := NetNameResolver addressForName: 'foo' timeout: 20.
    (NetNameResolver useOldNetwork and: [result = #[0 0 0 0]])
        ifTrue: ["Signal failure"].
    (NetNameResolver useOldNetwork not and: [result isNil])
        ifTrue: ["Signal failure"].

?
