How many next-header extensions can an IPv6 packet contain?
I read here that it can contains:
None, one, or more.
which isn't very informative.
Below is a reference to an IPv6 packet I'm looking at in Wireshark.
My reasoning is that, since an IPv6 packet can be, at most 65,535 bytes, it can contain (65,575 - 40) / 8 next-header extensions if the packet were to be made up of no data and entirely headers. What is a "reasonable" upper limit in practice?
