Parallel Internet measurement utility

Edit Package scamper
https://www.caida.org/tools/measurement/scamper/

Scamper is a program that is able to conduct Internet measurement
tasks to large numbers of IPv4 and IPv6 addresses, in parallel, to
fill a specified packets-per-second rate. Currently, it supports the
well-known ping and traceroute techniques, as well as MDA traceroute,
alias resolution, some parts of tbit, sting, and neighbour discovery.

Scamper can do ICMP-based Path MTU discovery. scamper starts with the
outgoing interface's MTU and discovers the location of Path MTU
bottlenecks. scamper performs a PMTUD search when an ICMP
fragmentation required message is not returned to establish the PMTU
to the next point in the network, followed by a TTL limited search to
infer where the failure appears to occur.

* update to version 20240503:
 * scamper:
   * improvements with -N squeries; let -Q send all probes when using -N.
     add -H wait-probe-hop, which specifies the minimum delay between
     probes with the same TTL.  identify the hop that would have caused
     traceroute to stop when not using -N so that a normal traceroute
     path with one hop representing the destination or stopping hop in
     the path is rendered.  in the json output, put extra hops beyond
     the stopping hop into a extra_hops array.
   * make ring-nolocked the default when using -O ring.
   * improvements with udpprobe: provide ability to send multiple copies
     of the same payload, add json output, reuse available UDP sockets
     where possible.
   * consistently set and record the IPv4 tos and IPv6 tclass fields for
     both ping and trace.
   * fix warts.bz2 and warts.xz output, which could previously use all
     available space on the file system.
   * speed up rendering of byte arrays as hex in json output.
   * fix obtaining IPv6 hoplimit on received packets on MacOS.
   * record the name of the interface that received IPv4 and IPv6 ICMP
     responses in ping.
   * add TXT queries to host command; add chaos query class; add
     DNS-over-TCP.
   * fix use of ctype functions according to netbsd (cast all parameters
     to unsigned char).  make pass through use of ctype functions to do
     ctype function calls last in most logical statements.
   * cleanup scamper_file_warts.h so that only necessary struct
     definitions are in that header.
 * libscamperfile:
   * add new functions, bump library version due to udpprobe changes.
