IPv6 Migration Auditor
A network assessment tool that scans an enterprise fleet and identifies every ARP-dependent device and IPv4-only workflow that is blocking an IPv6-only rollout.
enterprise network architects and infrastructure leads planning IPv6-only rollouts
- Passive network scan that inventories IPv4-only hosts, ARP-storm sources, and legacy DHCP clients
- Phased migration plan with a per-subnet cost-and-risk score and recommended cutover order
- Compatibility checks against the new 192.0.0.11 sentinel host behavior to find hosts that need an OS patch
- Executive dashboard showing projected address-space savings and ARP-related incident reduction
The IETF just closed the host first-hop gap with a sentinel value that lets operators drop ARP without breaking legacy hosts, but the migration is only safe after a real audit
RIPE Labs piece (July 2026) and IETF draft-vanmook-intarea-ipv6-resolved-gateway (v3, adoption call after IETF 126) confirm real operator pain, but HN submission got only 16 points/0 comments and IPv6-only rollouts remain a niche within enterprise networking.A Farewell to ARPs: IPv4 Service on IPv6-Only Networks ↗A Farewell to ARPs - IPv6 resolved gateways (IETF session) ↗
Route 128 is a direct IPv6-migration platform competitor, Erion sells IPv6 audit consultancies, and Forward Networks/RapidFire offer general network assessment, but no focused scanner specifically identifies ARP dependencies and IPv4-only workflows for IPv6-only rollout readiness.Route 128 — IPv6 Migration Platform ↗IPv6 Audit Consultancy - Erion Ltd ↗Forward | Best-in-Class Network Digital Twin Software ↗
Route 128 markets '80 hours not years' (implying premium consulting-tier pricing), Erion runs paid audit engagements, and Forward Networks sells enterprise network digital twin software; willingness to pay exists but buyers are small in number and the tool likely lives as a feature inside a larger platform.Route 128 — IPv6 Migration Platform ↗IPv6 Audit Consultancy - Erion Ltd ↗Forward | Best-in-Class Network Digital Twin Software ↗
IPv4 secondary-market prices, ARP operational pain at scale (the RIPE piece cites 10K hosts generating 500K ARPs/sec), and an IETF draft entering adoption make the problem durable, but enterprise IPv6-only rollouts historically stretch over many years and adoption is gradual.A Farewell to ARPs: IPv4 Service on IPv6-Only Networks ↗
ARP sweeping and device fingerprinting via SNMP/NetFlow/scapy is tractable for a small team, but reliable 'IPv4-only workflow' identification across an enterprise fleet requires traffic baselining, DHCP/fingerprint DBs, and integrations with multiple IPAM/AAA vendors — moderate build, not trivial.
