Difference between ipv4 and ICMP packet

Hello,

I was sending different type of network packet toward a host. And I discover that I could send Ipv4 packet. My questions are: 1)What is the purpose of an IPv4 packet ? 2)Is that a packet malformed by default ?

I can provide more details if needed :)

Thanks
