Packet Analyzer — ASN & BGP Route Lookup
BGP routing ownership snapshot — bgp-route backend, not packet capture analysis
How to Use This Tool
- Enter a public IPv4 address, domain, or ASN from log or alert context.
- bgp-route resolves domains and queries BGPView registry data.
- ASN input fetches up to twenty ipv4_prefixes when prefixes API succeeds.
- IP input maps address to originating asn, org, and country.
- Review asn, organization, prefixes, prefixCount, and note.
- Pair with traceroute and mtr-path-analyzer for path context on same target.
About This Tool
Packet analyzers dissect Ethernet, IP, TCP, UDP, and application payloads from PCAP files or live capture interfaces — Wireshark, tcpdump, and Cloud PCAP appliances are canonical tools. VSPIC packet-analyzer is transparent about scope: it calls the bgp-route action with query input — IPv4, resolvable domain, or ASN — returning ASN registry metadata, organization, country, and sample ipv4_prefixes with prefixCount on ASN queries — identical backend to bgp-route-lookup and tcp-header-analyzer.
There is no PCAP upload, protocol decode tree, or live capture on this page. Paste PCAP analysis notes into generic-text workspace tools or use Wireshark locally. Use this page when incident logs include IP addresses needing ASN ownership context without available packet captures.
Common use cases
- •Measure download and upload speed
- •Test open ports on a home router or server
- •Trace routing paths to diagnose latency
Why use VSPIC for ?
- Quick ASN ownership when PCAP is unavailable during triage.
- Sample prefix list on ASN queries for provider verification.
- Consistent bgp-route JSON with bgp-route-lookup for automation.
- Domain and IPv4 flexible input from firewall and IDS alerts.
- Free instant snapshot — no account required.
- Honest limitation disclaimers prevent false PCAP expectations.
Packet analysis versus BGP lookup
True packet analysis requires capture files or tap interfaces decoding protocols layer by layer. Our page performs bgp-route registry lookup — who originates routes for an IP — useful when alerts reference addresses without attached PCAP.
Document in tickets that ASN results came from bgp-route, not frame dissection.
What bgp-route returns
IP queries: asn, org, country, prefix hints. ASN queries: registry plus ipv4_prefixes samples and prefixCount. note documents prefix API failures.
Relationship to tcp-header-analyzer
packet-analyzer and tcp-header-analyzer share action bgp-route with identical JSON — packet versus TCP header SEO vocabulary differences only.
Follow-up with path tools
traceroute and mtr-path-analyzer add hop-level latency and loss when reachability questions accompany ownership triage — still not PCAP, but complementary.
Relationship to bgp-route-lookup
packet-analyzer and bgp-route-lookup share action bgp-route. Prefer bgp-route-lookup for routing research SEO; this page serves packet analyzer search demand honestly.
PCAP workflow reminder
Export suspicious flows in Wireshark, analyze locally on authorized captures. Use connection-stability-test generic-text workspace to paste probe output notes.
API action bgp-route
GET /ip-tools/api/extended?action=bgp-route&query=8.8.8.8. Chain with other extended actions in separate rate limit budgets.
Authorized use
Analyze captures only on networks you monitor with permission. BGP registry queries are passive.
Important notes & limitations
- Does not analyze packets, PCAP files, or protocol payloads.
- No Ethernet, IP, TCP, or UDP field dissection.
- Single-query BGP snapshot — not continuous traffic analysis.
- Prefix data reflects BGPView index — not live capture statistics.
- Use Wireshark for authoritative packet analysis on authorized captures.
