MAC Address Analyzer — BGP Route & ASN Lookup

BGP and ASN routing context — bgp-route backend, not Layer-2 MAC frame analysis

How to Use This Tool

  1. Enter a public IPv4 address, domain, or ASN like AS15169 or 15169.
  2. Query validation accepts IP-shaped, domain-shaped, or ASN-shaped input.
  3. bgp-route resolves domains to IPv4 before BGPView registry lookup.
  4. ASN queries fetch prefix samples with prefixCount when API succeeds.
  5. IP queries map address to originating ASN, org, and country fields.
  6. Review asn, organization, prefixes, prefixCount, and note fields.

About This Tool

True MAC address analysis inspects Layer-2 frames — source and destination MAC, VLAN tags, OUI vendor bits, and locally administered flags from switch mirrors or packet captures. VSPIC is transparent: mac-address-analyzer calls the bgp-route action with your query — IPv4, resolvable domain, or ASN — returning ASN registry metadata, organization, country, and up to twenty sample IPv4 prefixes when prefix enumeration succeeds — identical backend to bgp-route-lookup and asn-peering-lookup.

There is no MAC string input, OUI registry lookup, or Ethernet frame parsing on this page. For IEEE vendor resolution on MAC addresses, use mac-address-lookup. For OUI note collation, use oui-lookup generic-text workspace. This page serves MAC analyzer search demand while explaining bgp-route limitations honestly.

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 ?

  • Routing ownership context when correlating IP logs with network investigations.
  • ASN and org fields for provider escalation alongside MAC inventory work.
  • Sample prefix list for peering research on ASN input.
  • Domain and IPv4 input with automatic resolution.
  • Same reliable bgp-route path as bgp-route-lookup.
  • Free instant lookup — no account required.

MAC analysis versus BGP route lookup

Layer-2 MAC analysis reads CAM tables, 802.1X logs, and Wireshark Ethernet headers. Our page performs BGP and ASN registry lookup via bgp-route — answering who originates routes for an IP, not what vendor manufactured a MAC address.

Pair mac-address-lookup for OUI resolution with this page when IP-to-ASN context helps abuse or hosting attribution for the same incident.

What bgp-route returns for IP input

IPv4 query returns asn, name, org, country, ip, and prefix association. Use org field when escalations require provider identification during network investigations that also involve MAC inventory.

Absence of prefix detail on IP-only queries is normal — full prefix tables appear primarily on ASN-shaped input.

What bgp-route returns for ASN input

ASN queries trigger prefix enumeration when BGPView prefixes API succeeds — returning up to twenty ipv4_prefixes samples and prefixCount total. Registry metadata includes organization and country.

When prefixes API fails, registry metadata still returns with note about route detail availability.

Relationship to mac-address-lookup

mac-address-lookup resolves MAC strings to IEEE vendor names — the tool operators expect for MAC analyzer workflows. mac-address-analyzer shares bgp-route JSON with bgp-route-lookup for IP and ASN routing context.

Use both when triaging: MAC vendor from mac-address-lookup, hosting ASN from bgp-route on related IPv4.

Relationship to bgp-route-lookup

mac-address-analyzer and bgp-route-lookup both call action bgp-route with identical JSON. bgp-route-lookup uses routing SEO vocabulary; this page frames MAC analyzer search terms with explicit limitation disclaimers.

API GET /ip-tools/api/extended?action=bgp-route&query=8.8.8.8 on both.

Operational workflows

NAC teams identify unexpected MAC vendors via mac-address-lookup, then map gateway or DHCP server IP through bgp-route for upstream provider context on multi-site rollouts.

Document which tool answered which question in tickets — MAC vendor versus IP ASN.

Domain input behavior

Domains resolve to current public A record IPv4 before ASN mapping. CDN edge IPs may differ from origin — use origin-ip-finder when CDN obscures resolution.

API action bgp-route

GET /ip-tools/api/extended?action=bgp-route&query=8.8.8.8 or query=AS15169. Parse asn, org, prefixes, prefixCount, note.

Not a substitute for MAC address input — query parameter expects IP, domain, or ASN.

Important notes & limitations

  • Does not analyze MAC addresses or Ethernet frames — bgp-route only.
  • No OUI vendor lookup — use mac-address-lookup for MAC strings.
  • Prefix lists reflect BGPView snapshots — not live router tables.
  • IPv6-only hosts without IPv4 A records may not resolve from domain input.
  • Routing metadata does not map IP to physical switch port MAC tables.

Frequently Asked Questions

Yes. VSPIC offers this MAC address analyzer at no cost with no account required. Results load in real time.

We do not permanently store your queries on our servers. Some tools run entirely in your browser; others fetch public data for the request only.

Yes. Open the page in any modern phone or tablet browser. Results work on Wi‑Fi and mobile data.

No. It runs bgp-route ASN lookup on IP, domain, or ASN. Use mac-address-lookup for MAC vendor resolution.

Yes. Both use action bgp-route with query parameter. JSON fields are identical.

This form expects IP, domain, or ASN. Paste MACs into oui-lookup or use mac-address-lookup.

SEO framing for search demand. Backend is bgp-route — we disclose that transparently.

Yes. AS15169 or 15169 returns registry metadata and sample prefixes when available.

bgp-route with the query parameter.
