Checklist: Static IP Questions for Business Internet before Ordering
Before you place an order, confirm the specific static IP details your provider will deliver and how they will be configured. The most important practical questions cover allocation type, quantity, routing and provisioning timing because mismatches between what your network expects and what the provider supplies cause configuration delays, downtime, or failed services. Use the checklist below to turn static IP business internet questions into a clear purchase and implementation acceptance plan.
Static IP Requirement Checklist — What to Confirm and Why it Matters
Allocation and Ownership
Exactly how many public IP addresses will you receive? Why it matters: The count determines subnetting, NAT needs, and how many devices you can expose directly. What to request: The exact allocation described on the order and in the circuit acceptance test.
Will the addresses be provider-owned, leased, or delegated to my organization? Why it matters: Ownership affects portability if you change providers and who can reassign addresses later. What to request: Written statement in the contract and the process for transferring addresses on termination.
Is the allocation IPv4, IPv6, or both? Why it matters: IPv6 changes firewall rules, routing, and addressing plans. What to request: The addressing plan and any support for dual-stack configurations.
Routing, Provisioning, and Integration
How will the IPs be routed to my equipment? Why it matters: Your edge device configuration depends on whether the provider routes a prefix to their gateway, provides a routed subnet, or expects you to run routing protocols. What to request: A clear description of the routing method and the IP addresses for the gateway and any next-hops.
Will the provider support BGP or static routing on the circuit? Why it matters: BGP is required for multi-homed designs and specific failover behaviors. What to request: Supported routing protocols, example configuration snippets, and any ASN requirements.
How are addresses mapped to physical network elements (VLANs, subinterfaces, or separate circuits)? Why it matters: Misunderstood VLAN or tagging can leave services unreachable. What to request: A network diagram showing VLAN IDs, expected interface configurations, and any tagging conventions.
When during provisioning will the IPs be active? Why it matters: If IPs are not provisioned at turn-up, you cannot complete firewall or service testing. What to request: A provisioning timeline and acceptance checklist that you can test against before the circuit is declared operational.
DNS and Reverse DNS (rDNS)
Who is responsible for forward DNS and for creating reverse DNS (PTR) records? Why it matters: Many services, such as mail and some VoIP trunks, require correct rDNS for authentication and reputation. What to request: The process and contact for creating rDNS entries and whether you can manage rDNS yourself.
Will the provider host DNS on your behalf or delegate delegation records to your DNS provider? Why it matters: Delegation affects failover and the operational ownership of name resolution. What to request: DNS delegation details and any SLA on DNS changes.
Firewall, NAT, and Service Exposure
Is the circuit NATed by the provider or are addresses publicly routable to your edge? Why it matters: Provider NAT can prevent inbound services or complicate VoIP/SIP and hosted application connectivity. What to request: Confirmation of public routability and any provider NAT behavior.
How should inbound services be secured and where will firewall configuration be applied? Why it matters: Placement of firewall/NAT affects where to apply rules and who is accountable for filtering. What to request: Recommendations for firewall placement and any provider-managed firewall options.
Will the provider support common service needs such as static IPs for SIP trunks or hosted VPN endpoints? Why it matters: Voice and VPN services often require predictable public IPs and consistent routing. What to request: Any special configuration or testing steps for Business Voice or VPN services.
High Availability, Failover, and Multi-homing
What happens to routing and reachable addresses during provider or circuit failover? Why it matters: Your chosen HA model determines whether services continue without manual intervention. What to request: Failover behavior documentation and recommended architectures for multi-homing if you plan redundancy.
Are public IPs portable between providers or circuits? Why it matters: Non-portable addresses add work and risk during provider changes. What to request: Portability policy and any fees or lead-time for transfers.
Operational Support and Change Management
What support level and escalation path applies to IP configuration issues? Why it matters: IP routing and configuration problems are time-sensitive; you need a clear support SLA and contact points. What to request: Technical escalation contacts and examples of response expectations for provisioning errors.
How are configuration changes handled after activation? Why it matters: Planned changes, like adding addresses or modifying routing, require coordination to avoid outages. What to request: Change window policies, required lead time, and a single point of contact for configuration changes.
Will the provider supply configuration artifacts for your network team? Why it matters: Having vendor-provided config snippets or diagrams speeds integration and reduces errors. What to request: Interface addresses, gateway, VLAN IDs, BGP sample configs, and a simple turn-up checklist.
Contract, Billing, and Lifecycle
How are static IPs billed and how does billing change over time? Why it matters: Billing model affects cost planning and decisions about how many addresses to request. What to request: Billing terms for initial allocation, increases, and early termination.
What are the on-contract terms for address reassignment or decommissioning? Why it matters: Decommissioning procedures affect cleanup and security posture. What to request: The documented decommissioning process and any lead times.
Testing and Acceptance Criteria
What acceptance tests will confirm the static IPs and routing are correct? Why it matters: Without a test plan you may not notice misconfigurations until services fail. What to request: A runbook for acceptance testing (ping/traceroute, BGP session status, rDNS checks, service-specific tests) and success criteria.
How to Use this checklist during procurement and turn-up
Use the checklist to build a short appendix to your purchase order that lists the confirmed answers. Ask the provider to include the same details in their provisioning ticket and handoff documentation. During turn-up, verify each checklist item before signing off on acceptance so configuration problems are caught early rather than after services are live.
Operational Considerations Beyond the Technical Spec
When reviewing static IP details, look beyond the technical specifications and consider the impact on day-to-day operations. Confirm who will handle troubleshooting when connectivity or routing issues occur, how changes will be coordinated with your security team, and what your internal runbooks must cover. Addressing these operational gaps early can help prevent post-activation outages and configuration disputes.
For business-grade circuits, document static IP provisioning requirements directly in your order for Business Internet to avoid ambiguous handoffs. If your setup relies on static addresses for phone systems, discuss your Business Voice or SIP trunking requirements during the same procurement process to ensure both services work together.
If you need a checklist for an RFP or purchase order, turn the key requirements into a one-page acceptance table and ask the provider to complete each field during provisioning.
