When to Choose Public IPv4 Over NAT for Business Customers

When to Choose Public IPv4 Over NAT for Business Customers

NAT suits most residential users. Business customers often need dedicated public addresses. How ISPs can segment offerings sensibly.

Different customers, different needs

Residential subscribers mostly consume content, which works well behind NAT. Business customers often run VPN gateways, remote access, cameras, servers or need fixed addresses for partner whitelists.

A tiered approach

  • Standard: CGNAT with IPv6.
  • Business: a dedicated public IPv4 address plus IPv6.
  • Business plus: a small public IPv4 block for multiple services.

Pricing

IPv4 addresses have a real market value. Pricing dedicated addresses accordingly helps ISPs recover cost and use scarce space wisely.

IPv6 as the default for growth

Encourage business customers to make services reachable over IPv6. It removes the address constraint for the future.

Operational clarity

Clearly document which customers are behind NAT and which have public addresses. It speeds up troubleshooting and lawful request handling.
