Ah yeah, these clowns. I distinctly recall, when rewriting the DNS record cache used internally at Google (note: not the resolver), thinking that surely no MX response would need more than 8KiB, and finding these jokers.

At Google scale, you don't just find edge cases, you find every edge case. I miss the days when Google actually bothered to support them, though.
