## What is PCAP Viewer?

PCAP Viewer turns your iPad into a network protocol analyzer. Open a pcap or pcapng file received by email, AirDrop or Files and explore it as on your desktop: a colorized packet list, a detail tree and a hex dump, all linked together.

Available in English and French.

EVERYTHING YOU NEED TO TROUBLESHOOT
• Packet list with sortable columns, rule-based coloring and custom columns
• Field-by-field details; tap a field to highlight its bytes, tap a byte to find its field
• 40+ protocols: Ethernet, VLAN, ARP, IPv4/IPv6, ICMP, TCP, UDP, DNS, DHCP, HTTP, TLS (SNI, certificates), SIP/SDP, RTP/RTCP, DTMF, NTP, QUIC, STUN, LLDP, STP…
• TCP analysis: relative sequence numbers, retransmissions, duplicate ACKs, zero window
• TCP reassembly (HTTP, TLS, SIP) and IPv4 defragmentation

DISPLAY FILTERS
• Familiar syntax: ip.addr == 10.0.0.0/8 && tcp.port in {80 443}
• contains, matches, slices eth.src[0:3], functions len(), count(), lower()…, layers ip.addr#2
• Live validation, field completion, history and saved filters
• "Apply as filter" and "Apply as column" on any field

VOICE OVER IP
• SIP call list with call state
• SIP and RTP flow (ladder) diagram
• RTP streams: loss, jitter, delta, DTMF and G.711 playback

STATISTICS AND TOOLS
• Protocol hierarchy, conversations, endpoints, I/O graph, expert info
• Follow TCP or UDP stream
• Find packet, go to packet, marks and time reference
• "Decode As…", editable coloring rules, import of filter and coloring files
• Export displayed or marked packets as pcap / pcapng

PRIVACY
Your captures stay on your iPad. The app collects no data and never connects to a server.

Sample captures are included to get started.
