If you see this message you intercept a packet that belongs to Manycast2.

If you are a network operator and you believe your servers may be experiencing problems due to our measurements, please consult the information below on what you can expect to see from us, and as a last resort how you can contact us to block our traffic.
We thank you in advance for working with us to resolve any issues and apologize in advance if we have inadvertently caused problems through our measurement.

Manycast2 is a project that aims to scan the IPV4 network address space to detect anycast instances.
We make use of ICMP echo request packets (ping) targeting USC/ICI hitlist IP addresses https://ant.isi.edu/datasets/ip_hitlists/.
We generate a very small amount of traffic (1 packet per each prefix, each 20 minutes) that should not affect your systems.
However, if this cause you inconveniences don't hesitate to contact us at:

# Script will generate one flow per thread (-t N)
#  - Same destination IP
#  - Fake source IPs for each flow (fixed based on thread number)
#
# Useful for scale testing on receiver, to see whether silo'ing flows
# works and scales.  For optimal scalability (on receiver) each
# separate-flow should not access shared variables/data. This script
# helps magnify any of these scaling issues by overloading the receiver.
