Final week’s IPv6 safety video launched the rogue IPv6 RA challenges and the same old countermeasure – RA guard. Sadly, IPv6 tends to be a splendidly extensible protocol, creating all kinds of alternatives for nefarious actors and safety researchers.

For years, the networking distributors have been furiously making an attempt to plug the holes created by the academically minded IPv6 designers in love with fragmented extension headers. Within the meantime, safety researches had completely no downside discovering one more bizarre mixture of IPv6 headers that may bypass any IPv6 RA guard implementation till IETF gave up and admitted one can not have “infinitely extensible” and “safe” in the identical sentence.

For extra particulars watch the video by Christopher Werny describing how one may use IPv6 extension headers to avoid IPv6 RA guard
