IPv6 Readiness Assessment &
Enterprise Migration

India has 1+ billion internet users but most enterprises still run IPv4-only. We assess your infrastructure, design a phased migration path, and deploy dual-stack security — with zero downtime.

Why Indian Enterprises Can't Ignore IPv6 Anymore

The math is simple — IPv4 offers 4.3 billion addresses for 8 billion people and 50+ billion devices. India alone has 1 billion internet users and 500 million IoT devices projected by 2026.

IPv4 is Unaffordable

IPv4 addresses now trade at $50+/IP in Asia-Pacific secondary markets, with a /24 block (256 IPs) costing well into the lakhs. Growing enterprises are paying more for addresses than for the hardware that uses them.

DoT Mandate Active

All new wireline connections must support IPv6 since December 2022. Government departments were required to migrate by June 2022. India targets 100% IPv6 readiness by 2030.

Invisible Attack Surface

Most enterprise networks already have IPv6 traffic — your ISP, OS, and devices enable it by default. Without proper IPv6 firewall policies, you have an unmonitored backdoor.

Our IPv6 Assessment Methodology

A rigorous 4-phase assessment that maps your entire infrastructure before a single change is made.

1
Infrastructure Audit

Inventory every router, switch, firewall, load balancer, and application. Identify devices that support IPv6, need firmware upgrades, or must be replaced.

2
Application Mapping

Test every business-critical application for IPv6 compatibility — ERP, CRM, VoIP, monitoring tools, DNS, DHCP, and custom in-house software.

3
Security Gap Analysis

Evaluate current firewall rules, IPS signatures, and monitoring tools for IPv6 readiness. Identify unmonitored IPv6 traffic already flowing through your network.

4
Migration Roadmap

Deliver a phased migration plan with timelines, budget estimates, risk assessment, and rollback procedures — tailored to your enterprise's specific infrastructure.

Migration Strategies We Deploy

Dual-Stack

RECOMMENDED START

Run IPv4 and IPv6 simultaneously on all devices. Full backward compatibility while progressively enabling IPv6. FortiGate's consolidated policy mode manages both stacks in a single rule set.

  • Zero downtime transition
  • Full IPv4 backward compatibility
  • Gradual application migration

NAT64 + DNS64

IPv6-ONLY NETWORKS

Deploy IPv6-only on the LAN and translate at the edge for IPv4-only servers. FortiGate's built-in NAT64 and DNS64 proxy handle translation transparently.

  • Eliminate IPv4 on internal networks
  • Reduce address management overhead
  • Best for greenfield deployments

Tunneling

BRANCH CONNECTIVITY

Connect IPv6 islands across IPv4-only WAN segments using 6in4, GRE, or IPsec tunnels. Ideal for branch offices with legacy WAN infrastructure that can't be upgraded immediately.

  • Works over existing IPv4 WAN
  • No WAN provider dependency
  • Quick to deploy for remote sites

With Ogma IPv6 Migration vs. Without

With Ogma

  • Complete infrastructure audit before any changes
  • IPv6 security policies deployed alongside IPv4
  • Zero downtime with phased migration
  • Continuous monitoring during and after transition
  • DoT compliance documentation included

Without Expert Migration

  • Unmonitored IPv6 traffic already on your network
  • IPv4 address costs rising 15-20% annually
  • DoT compliance risk for government contracts
  • Dual-stack without dual-stack security = blind spots
  • Application breakage from untested migration

Frequently Asked Questions

A typical assessment for a mid-size enterprise (500-2000 users, 3-10 sites) takes 2-3 weeks. This includes infrastructure inventory, application testing, security gap analysis, and delivery of the migration roadmap document. Larger enterprises with multiple data centers may require 4-6 weeks.

Most modern network equipment (manufactured after 2015) supports IPv6. Our assessment identifies exactly which devices need firmware upgrades versus replacement. FortiGate firewalls, for instance, have full IPv6 parity across all models — IPS, antivirus, web filtering, and application control all work on IPv6 traffic.

Yes — dual-stack is our recommended starting strategy. Both protocols run in parallel, allowing you to migrate applications one at a time with zero downtime. FortiGate's consolidated policy mode lets you manage both IPv4 and IPv6 in a single firewall rule, reducing operational overhead.

DoT mandates that all new wireline connections support IPv6 since December 2022. Government departments were required to complete migration by June 2022. India targets 100% IPv6 readiness by 2030. Enterprises selling to government or regulated sectors face increasing compliance pressure.

FortiGate's built-in NAT64 and DNS64 allow IPv6-only clients to seamlessly access IPv4-only servers during and after migration. Legacy applications continue working without modification while new infrastructure runs natively on IPv6.

IPv4 addresses in Asia-Pacific trade at $50+ per IP on the secondary market and have appreciated double-digits annually. A /22 block (1,024 IPs) is a major capex line and availability is shrinking. IPv6 addressing is free and unlimited. The one-time migration investment typically pays for itself within 18-24 months through avoided IPv4 procurement alone.
