No way to know with the information provided. If you provided a packet capture, Then we could do something with this...
Assuming 192.168.30.255 has a netmask of 255.255.255.0 or /24
This address would be the broadcast address.
An IP packet is a network data packet using Internet Protocol (IP) format.

There are two address fields. Source is the IP address the packet came from and destination is the IP address the packet is meant to be delivered to.
The IP protocol creates all IP packets.
The protocol field, in the IP header, identifies what kind of data is in the IP packet - the upper-layer protocol. For example, if the code is 6, that means that the data is a TCP segment.
It's recorded at the top of the IP packet header. 16 bit source and destination port.
When IP sends a packet, it receives a confirmation for each packet and, if needed, rebroadcast the packet. This makes it reliable. UDP does not get confirmation. It broadcast each packet only once and assumes that it get to you. This makes it less reliable then IP because it does not check for problems or rebroadcast.
An IP packet can contain data about the format of the internet header and the abstract parameters such as the header checksum. The IP packets also provide an internet time stamp.
