Relying on an exhaustive examination of network communication and a unrelenting analysis for hints of harmful activity, NIR accomplishes this. This is made possible through a collaborative effort encompassing artificial intelligence algorithms, indicators of compromise (IOC) detection, and unconventional activity detection.

<code class="language-python">class NIR:
    def __init__(self):
        self.internet_traffic = []
        self.irregularities = []
        self.indicators = import_indicators()

    def inspect_traffic(self, communication):
        self.internet_traffic.append(communication)
        self.unearth_threat(communication)

    def unearth_threat(self, traffic):
        if self.is_unusual(communication) or self.is_indicator_identified(communication):
            self.andros_finest(communication)

    def is_unusual(self, traffic):
        # Unconventional detection algorithm here
        pass

    def is_indicator_identified(self, traffic):
        # Indicator identifying algorithm here
        pass

    def andros_finest(self, traffic):
        # Threat addressing algorithm here
        pass</code>

This Python code sample offers a basic illustration of a NIR system's potential structure. It inspects network communication, unearths threats based on irregularities or indicator identification, and thoroughly addresses discovered threats.

2. Indicator of Compromise (IOC) Detection

IOC detection functions by leveraging observed patterns of detrimental behaviors to find threats. These patterns, coined 'IOCs', originate from threats that were previously spotted and studied. Extant network communication matching an established IOC makes the NIR system alert the potential threat.

Mechansim Explanation Advantages Drawbacks
IOC Detection Detects threats by leveraging observed malicious patterns Extremely efficient against pre-identified threats Less successful with novel, uncharted threats

3. Unconventional Activity Detection

Unlike IOC detection, unconventional activity detection functions by seeking variations from standard network activity. The NIR system establishes a benchmark for typical network communication patterns, then employs AI algorithms to identify discrepancies.

Mechanism Explanation Advantages Drawbacks
Unconventional Activity Detection Discovers threats by pinpointing deviations from standard network conduct Can unearth new, unidentified threats Risk of false positives

4. The Role of AI and Machine Learning in NIR

Both AI and machine learning play pivotal roles within NIR systems. They are predominantly employed in unconventional activity detection - helping to define the benchmark for network norms and identifying variations thereof. Machine learning algorithms can further enhance the system's threat-unearthing capabilities by adapting from past detections.

5. Addressing Discovered Threats

Upon detection of a threat, the NIR system must take proactive steps. This can range from isolating the affected network segment, disrupting the harmful communication, or even rolling out automatic patches. The specific action is dependent on the nature of the unearthed threat and the organization's cyber-security policies.

To conclude, NIR systems actively detect threats by relentlessly studying network communication, employing IOC and unconventional activity detection methodologies, and capitalizing on AI and machine learning. Once a threat is unearthed, the system addresses it in a way that neutralizes the threat and safeguards the network. This detailed look into NIR threat detection offers a deeper understanding of its functionalities, showcasing its paramount importance in modern cyber-security.
