Hello Kirill,

 Here's the tcpdump on HN:


11:38:39.651963 00:1b:d5:2c:bf:38 > ff:ff:ff:ff:ff:ff, ethertype IPv4
(0x0800), length 350: 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request
from 00:1b:d5:2c:bf:38, length 308

11:38:39.669960 00:08:02:ac:36:20 > ff:ff:ff:ff:ff:ff, ethertype IPv4

and on VPS it's visible as:

11:38:39.669971 00:08:02:ac:36:20 > ff:ff:ff:ff:ff:ff, ethertype IPv4
(0x0800), length 342: 172.17.8.254.67 > 255.255.255.255.68: BOOTP/DHCP,

can't find any sign of this packet in /var/log/messages, it looks like
everything in /var/log/messages is completely unrelated to dhcp, some of
those are vrrp heartbeat, others - SNAP, 

it looks like this:
grep -i 00:08:02:ac:36:20 /var/log/messages

Oct  1 10:48:09 dfw1 kernel:   src = 00:1b:d5:84:90:92:, dst =
00:08:02:ac:36:20:
Oct  1 10:59:42 dfw1 kernel:   src = 00:1b:d5:84:7a:1f:, dst =
00:08:02:ac:36:20:

no sign of similiar packet on 11:38:39,
