Hallo,
The output of my grep command is:
# grep -i "sshd" /root/access.report | egrep -o
'(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-

Adding the --debug option shows the issue.
I.e. the '.' being considered as part of a number:
$ sort --debug -rbn -s ips
sort: text ordering performed using ‘en_IE.UTF-8’ sorting rules
sort: note numbers use ‘.’ as a decimal point in this locale

Taking the example for sorting IPv4 addresses from the manual,
shows the desired comparisons being performed:
$ sort --debug -t '.' -k 1,1rn -k 2,2rn -k 3,3rn -k 4,4rn -u ips
sort: text ordering performed using ‘en_IE.UTF-8’ sorting rules
sort: numbers use ‘.’ as a decimal point in this locale
