One particular bug that has appeared exists not in Mozilla, but in IPv6-capable DNS servers: an IPv4 address may be returned when an IPv6 address is requested. It is possible for Mozilla to recover from this misinformation, but a significant delay is introduced.Under certain versions of OS X, this bug is compounded by another bug wherein the OS still makes IPv6 DNS requests even if IPv6 support is disabled. A significant delay is introduced in all connections requiring DNS lookups while the OS and the DNS server exchange unnecessary (or redundant) queries and responses to resolve the address.
Kann man sich gar nicht ausdenken, sowas.
