There are three "classes" of IPv4 subnets. Essentially, these refer to which "octet" is set.
Class A: A /8 network (netmask 255.0.0.0) - the first octet is set and the rest belong to you. i.e. 128.x.y.z. You have 256x256x256/2^24 IPs available here.
Class B: a /16 network (netmask 255.255.0.0) - the first two octets are set and the rest belong to you, i.e. 128.67.y.z. You have 256x256/2^16 IPs available.
Class C: a /24 network (netmask 255.255.255.0) - the first three octets are set and the use of the fourth is yours, i.e. 128.67.4.z. You have 256/2^8 IPs available.
It's possible your question may have meant types of addresses used (for routing purposes). There are broadcast addresses (send a packet to everyone on my local network), unicast (basically point-to-point connections, the most common) and multicast (senders/receivers communicate through a multicast IP, sending one packet to many destinations with just one transmission).

What is the size of today's standard (IPv4) IP address?
The size of an IPv4 address is 32 bits, or 4 bytes.
What is the difference between your IPv4 address and your IP address?
IP is the internet protocol that uniquely identifies a system on a network and there is no difference between IP and IPv4 infact IPv4 is a version of like IPv6.

Which characteristic describes an IPv6 enhancement over IPv4?
While IPv6 is based on IPv4, it is superior. The main characteristic that shows its enhancement over IPv4 is that it processes faster.
What is the number of bytes in ipv4 address represented in dotted decimal notation?
An IPv4 address represented in dotted decimal notation consists of four octets, each ranging from 0 to 255. Each octet is 1 byte, so the total size of an IPv4 address is 4 bytes. Thus, an IPv4 address in dotted decimal notation is 4 bytes in size.
What is the broadcast address on IPv4 networks?
The broadcast address on IPv4 networks is the subnet address, padded on the right with ones. For example, if the subnet address is 192.168.x.y, with a subnet mask of 255.255.0.0, then the broadcast address is 192.168.255.255.
What three facts are true about the network portion of an IPv4 address?
The IPv4 address is identical for all hosts in a broadcast domain. The IPv4 addresse varies in length. The IPv4 address is used to forward packets.
