Well here is a vote that ICMP checksums receive some attention. :)

Thanks for the reference.  Stevens vol. I already covers the good points,
but the RFC is always good to read.

Are there any other references, especially ones that discuss
implementation of ICMP address mask request/response?  I'm looking at
a trace of some address mask pairs that are going /way/ beyond the
local subnet or related networks (specific /32 address, not the all
subnets broadcast), and I'm trying to understand why.  In the modern
networking world, address mask requests seem superfluous, and at the
least shouldn't extend very far beyond the local subnet.

But this isn't "Networking 204".
