Dear Concerns, I found that the driver contains public IP(169.254.10.240), which leads to my binary  with public IP too, which is not what I want. What is the function of this IP, and could the community delete it for security reasons? >>[root@localhost dpdk-19.11]# grep "169.254.10.240" -r  ./ >>./drivers/net/ark/ark_pktgen.c: {{"dst_ip"}, OTSTRING, .v.STR = "169.254.10.240"}, >>./drivers/net/ark/ark_pktchkr.c: {{"dst_ip"}, OTSTRING, .v.STR = "169.254.10.240"} Thanks & Regards, Peanut_Huang
