IP fluctuations were detected.

Solution:

Add to/etc/sysctl.conf

net.ipv4.conf.default.arp_ignore = 1

Meaning: Determines the different ways in which the response is sent. ARP requests 0-(default) represents the destination IP address anywhere, configured on any interface. 1-Replies only to incoming interfaces configured on destination IP addresses that are local addresses.

net.ipv4.conf.all.arp_ignore = 1 Meaning: Same as above

after sysctl -p

Add the mac address to the/etc/sysconfig/network-scripts/ifcfg-eth file, which can be viewed with ifconfig.
