I have fired command for IPv4 only, even then I am getting IPv6 lease as well

Please check

dhcpcd  -t 130 -L -i abc -o 2 -o 3 -o 4 -o 7 -o 42 -o 6 -o 12 -o 15 -o 66 -o 120 -o 43

You need to add -4 to get IPv4 only.

Without seeing the wireshark traces I'll assume that a node is incorrectly claiming the unspecified address.
I also won't rule out a bug in dhcpcd-6.11.0
You can try disabling ARP checking with the -A flag.
