2019-11-25 · It is a common mis-understanding that there is no IPv6 fragmentation because the IPv6 header doesn't have the fragment-offset field that IPv4 does; however, it's not exactly accurate. IPv6 doesn't allow routers to fragment packets; however, end-nodes may insert an IPv6 fragmentation header 1.. As RFC 5722 states 2, one of the problems with fragmentation is that it tends to create security holes.
2014-5-7 · 2. Traditional Neighbor Discovery and IPv6 Fragmentation The only potential use case for IPv6 fragmentation with traditional (i.e., non-SEND) IPv6 Neighbor Discovery would be that in which a Router Advertisement must include a large number of options (Prefix What is the difference between packet fragmentation in One of the innovations introduced by IPv6 is the elimination of hop-by-hop packet fragmentation. With the new protocol, fragmentation is managed at the ends by means of a special extension header. More specifically, there are two main differences: Difference one is the fields for handling fragmentation are not in the basic IPv6 header but are What are the benefits of removing fragmentation from IPv6? 2019-11-25 · It is a common mis-understanding that there is no IPv6 fragmentation because the IPv6 header doesn't have the fragment-offset field that IPv4 does; however, it's not exactly accurate.

As RFC 5722 states 2, one of the problems with fragmentation is that it tends to create security holes. Dealing with IPv6 fragmentation in the DNS, Part 2 | APNIC 2017-8-29 · The IPv6 specification requires that a conformant IP network path be capable of passing an IPv6 packet of up to 1,280 bytes without requiring packet fragmentation. What it fails to specify is the minimum fragmented packet size that an end host can receive.
IPv6 and Fragmentation When it came time to think about the design of what was to become IPv6, the forward fragmentation approach was considered to be a liability. And while it was not possible to completely ditch IP packet fragmentation in IPv6, there was a strong desire to redefine its behaviour.

2019-4-22 · In IPv6 the "forward" fragmentation works slightly differently than in IPv4. The intermediate routers are prohibited from fragmenting the packets, but the source can still do it. This is often confusing - a host might be asked to fragment a packet that it transmitted in the past.
