Issue is weird:

Company's JetsonTX2 jacket of Ubuntu 16.04 LTS, through cable and wireless bridge is linked together, I set in the/ec/network/interfaces eth0 static IP for 192.168.1.165, and cancel the NetworkManager management of eth0, but probably in a few minutes after the system startup, IP will be amended by the original 192.168.1.165 192.168.1.142,

If you enable NetworkManager eth0 management and NetworkManager set the IP address to 192.168.1.165, and then restart the NetworkManager service or restart JetsonTX2 development board, the IP address is 142, if use NetworkManager set the IP address to 192.168.1.142, IP addresses will become 192.168.1.140,

Then use sudo apt - get purge network manager - delete NetworkManager, again through the/etc/network/interfaces will be set for a static IP for 192.168.1.142 eth0, restart the networking services or restart JetsonTX2 development board after the IP address is indeed a 192.168.1.142, at this time the ifconfig -a no eth0: avahi, only eth0, about 5 to 10 minutes, however, eth0 IP will disappear, and appear eth0: avahi, and eth0: avahi IP for 169.254.10.68,

Internet avahi - caused by the daemon, so I sudo apt - get pureg avahi - daemon, what does not, however, problems still,
Perform online said sudo update - rc. D - f avahi - daemon remove, also no use, however, question remains the same,

Anyone can think of other may change the IP address of the service or application? Thank you!
