Check firewall-cmd or iptables -L (depending on linux release and type) rules for specific rules, containing IP addresses in questions.
This should help, if linux firewall is used.
If not, other advice given here (ss netstat nmap) should provide reasonable info.
Please, when asking such question in future, please specify your operating system and version.
This will help us help you.
Regards
Peasant.

NAME
mason - interactively create a firewall
SYNOPSIS
mason < logfile > rulefile
DESCRIPTION
This manual page briefly documents the mason command.
mason interactively generates a set of firewall rules for a Linux-based firewall. This is done by turning on full IP logging, watching the
logs for connections, and generating rules describing the connections seen. mason is familiar with most of the quirks of various connec-
tion types (such as ftp and IRC), and can output rules for 2.0.x ipfwadm, 2.2.x ipchains, and Cisco packet filters.
mason operates by reading in log file information from standard input and writing firewall rules to standard output. This allows mason to
work offline or on a separate system. Real-time firewall generation can be achieved with a command like tail(1).
Most users will want to run mason with a user-friendly interface such as mason-gui-text(1).
ENVIRONMENT
mason is configured using the following environment variables.
ECHOCOMMAND
Sets the type of firewall rules that mason should output to standard out. Allowed values include "ipfwadm" and "ipchains". By
default, mason outputs whatever kind of rules are supported by the currently running Linux kernel.
DOCOMMAND
Sets the type of firewall rules that mason should run immediately when a rule is generated. Allowed values include "ipfwadm" and
"ipchains". By default, mason outputs whatever kind of rules are supported by the currently running Linux kernel.
HEARTBEAT
If set to "yes", mason will output a "+" or "-" to standard error whenever a rule generated by mason has been triggered.
DYNIP Set this to the list of interfaces that have dynamically assigned addresses, separated by spaces.
