Can you point to where it says that explicitly? I see in ssh_config(5):
HostName
Specifies the real host name to log into.
Note that "real host name" is in the singular.
It then does make use of the plural:
This can be used to specify nicknames or abbreviations for hosts
but I read that as meaning that you can configure multiple hosts, each
with its own HostName, e.g.
Host foo
HostName 192.0.2.1
Host bar
HostName 192.0.2.2
Similarly:
Arguments to HostName accept the tokens described in the TOKENS
section. Numeric IP addresses are also permitted
To me this is talking about multiple HostName entries in the same
ssh_config file, each belonging to a different Host, rather than one
HostName allowing multiple IP addresses. However I guess it could be
read either way.
