any/local-ipv6-lookup, if fixable, would be one such workaround. (See
previous glibc changelogs.)

Depends on the situation. You wouldn't want to give a host that address,
but it might be quite reasonable to have an A record resolve to that IP
address for the purpose of naming the network. The resolver isn't in a
position to distinguish those cases, IMO.
(Besides, who knows whether 1.0.0.0 is the only possible erroneous value
for this kind of broken router? Only the vendor, really.)
