Hi. This is assuming that the particular network switch which guam96913's co-worker is using (standalone and only a laptop connect to it) has built-in DHCP server capability. This will typically be found on a layer 3 network switch / core switch, and network routers.
Otherwise, if it is only a layer 1 or layer 2 switch / edge switch with no DHCP capability, then the switch will not have an IP address as it is not possible to assign one to this type of switch, nor will the switch have the ability to assign IP addresses to nodes connected to it. An exception to this will be if the switch is a managed switch permitting the assignment of an IP address to the switch for management access only.
To be sure, we would need to know the make and model of the network switch in question.
