When I use nocloud datasource with numeric hostname like 1234,
it shows errors as follow,

614 else:

before utilize lhost, it needs to convert to string type like
-> net.is_ipv4_address(str(lhost))
-> str(lhost).split(".")
because when hostname is numeric only, lhost type would be integer by default
in python.
