## Questions this post answers

### What does RFC 9098 say about IPv6 extension headers?

RFC 9098 documents the operational implications of IPv6 extension headers, concluding that they cause significant problems in practice. It took over seven years of IETF work to publish. The RFC's title is deliberately diplomatic, but the operational reality it describes is that IPv6 extension headers are widely problematic for network operators — they are frequently dropped or mishandled by middleboxes and routers.
