Lease vs. Buy for ISPs & Telecom
Choose the acquisition model that fits your network strategy
| Upfront Cost | Monthly Cost | Ownership | Flexibility | Best For | |
|---|---|---|---|---|---|
| Lease | None | $0.40–0.50/IP | Usage rights during term | High — scale with subscriber growth | New market entry, seasonal capacity, CGNAT supplement |
| Buy | $26–32/IP | None | Full permanent ownership | Low — fixed allocation | Core subscriber base, long-term network assets |
Most ISPs benefit from a hybrid strategy: purchase blocks for your core subscriber base to build a permanent asset, and lease additional capacity for new market rollouts or seasonal peaks. This approach protects your balance sheet while ensuring you never run out of addresses.
