man sshd_config is your friend, look at Match
Match Introduces a conditional block. If all of the criteria on the
Match line are satisfied, the keywords on the following lines
override those set in the global section of the config file,
until either another Match line or the end of the file.
The arguments to Match are one or more criteria-pattern pairs.
The available criteria are User, Group, Host, and Address. The
match patterns may consist of single entries or comma-separated
lists and may use the wildcard and negation operators described
in the PATTERNS section of ssh_config(5).
The patterns in an Address criteria may additionally contain
addresses to match in CIDR address/masklen format, e.g.
“192.0.2.0/24” or “3ffe:ffff::/32”. Note that the mask length
provided must be consistent with the address - it is an error to
specify a mask length that is too long for the address or one
with bits set in this host portion of the address. For example,
“192.0.2.0/33” and “192.0.2.0/8” respectively.
