Frequently Asked Questions

Find Quick Answers

What file formats does the packet analyzer support?

The tool supports standard PCAP (Packet Capture) files, which is the most common format for network packet capture. You can also paste raw packet data in hexadecimal format for manual analysis.

Can I analyze live network traffic with this tool?

No, this is an offline analyzer that processes captured packet files or manually entered data. For live traffic analysis, you would need specialized software that can capture packets directly from your network interface.

What protocols can the analyzer detect?

The tool detects common network protocols including TCP, UDP, HTTP, HTTPS, DNS, DHCP, ARP, ICMP, FTP, SSH, and more. It analyzes packet headers to identify protocol types and provides detailed information about each.

Is my packet data secure when using this tool?

Yes, all analysis is performed either locally in your browser or on our secure servers. We do not store or share your packet data. For sensitive information, you can use the client-side analysis option which processes everything locally.
