Multi-Dialing Blocker

Some malicious users acquire a large number of IP addresses from the same subnet by using multi-dialing or similar methods.
Although ARB (Automatic Range Blocking) has nearly the same functionality as this module, it only activates when a ban condition is met. In contrast, the multi-dialing blocker actively monitors connected peers without waiting for a ban command.

When the number of IP addresses from the same subnet exceeds the specified threshold and these IPs are connected to the same torrent, subnet banning will be initiated.

Hunting​

If an IP is determined to be using multi-dialing, it will continue to search for all other peers within the same subnet, ignoring cache time limits.

Enabling this feature will consume some additional runtime memory.

Configuration File​

  # Multi-dialing Blocker
  # Multi-dialing blocker
  multi-dialing-blocker:
    enabled: true
    # Ban duration in milliseconds, use default to follow global settings
    ban-duration: 1296000000
    # IPV4 prefix length
    # The number of common bits in the IP address to consider as the same subnet. The fewer bits, the larger the range. Usually, no need to modify.
    subnet-mask-length: 24
    # IPv6 prefix length
    subnet-mask-v6-length: 60
    # Maximum number of IPs allowed to download the same torrent from the same subnet, positive integer
    # To avoid false positives caused by DHCP reassigning IPs or multiple users in the same area downloading the same torrent
    tolerate-num: 5
    # Cache lifespan in seconds
    # All connected peers will be recorded in the cache. DHCP reassigns IPs periodically, and if the cache time is too long, false bans may occur.
    cache-lifespan: 86400
    # Keep hunting
    # If an IP is flagged as multi-dialing, should the system ignore the cache lifespan and continue hunting for other IPs in the same subnet?
    keep-hunting: true
    # Hunting duration in seconds
    # Effective only when keep-hunting is enabled, similar to cache-lifespan, this controls the duration of cached data for hunted IPs.
    keep-hunting-time: 2592000
