Destination IP addresses not found by IP Lookup


When I use IP Lookup for destination IP addresses of apps accessing the internet, as identified by BDTS, they can't be identified. For example is destination for comm''s from HxTsr.exe. If i delete the last two characters IP Lookup identifies the destination as MS in Washington. LockApp.exe has destination IP address as 2A02:26F0:FD00:02B3:0000:0000:0000:1011 but this is totally wrong format for an IP address?? Any ideas?

    Understanding the Issues

    • IP Address Formats:
      • IPv4: These are the familiar addresses like They are divided into four octets (numbers from 0 to 255) separated by dots. The "/0" at the end of your example is CIDR notation, indicating the size of the network, and is not part of the IP address itself.
      • IPv6: These are newer addresses like 2A02:26F0:FD00:02B3:0000:0000:0000:1011. They are longer and use hexadecimal characters (0-9 and A-F) separated by colons.
    • Bitdefender's Output: It seems Bitdefender might be appending extra characters or misinterpreting the IP addresses in some cases.
    • IP Lookup Tools: Most IP lookup tools expect a standard IPv4 or IPv6 address format. If the input is invalid, they might not provide accurate results.


    1. Clean the IP Addresses: Before using any IP lookup tool, make sure to remove any extra characters or notations from the IP addresses that Bitdefender provides.
      • For the example "", use just "".
      • The IPv6 address "2A02:26F0:FD00:02B3:0000:0000:0000:1011" is already in the correct format.
    2. Verify IP Address Validity: Use an online tool or a command-line utility to check if the cleaned IP addresses are valid:
      • Online Tools: There are many websites that can verify IP address formats. Search for "IP address validation tool."
      • Command Line (Windows): You can use the ping command. If the IP is valid, it will attempt to ping the address.
    3. Use Reliable IP Lookup Tools: Choose reputable IP lookup services that handle both IPv4 and IPv6 addresses correctly.

    Additional Considerations

    • Firewall Rules: If Bitdefender's firewall is blocking traffic to these addresses, that could explain why you can't get lookup results. Temporarily disable the firewall and try again.
    • Dynamic IPs: Some servers use dynamic IP addresses that change frequently. The lookup results you get might be accurate only for a short period.
