**Section 1: Account Information** - **Customer ID:** 98765 - **Full Name:** Jane Doe - **Email Address:** [email protected] **Section 2: Server / Service Information** - **Primary Server ID / Hostname:** DEDI-ATL-54321 - **Service Location:** US-East (Atlanta, GA) **Section 3: IP Address Request** - **IP Version Requested (IPv4 or IPv6):** IPv4 - **Subnet Size Requested:** /28 **Section 4: Detailed Justification** - **Web Servers (SSL):** 10 - **Mail Servers:** 1 - **Nameservers (DNS):** 2 - **Virtualization/Containers:** 0 - **Other Services:** 0 - **Detailed Service Description:** We are a web hosting reseller. This /28 subnet (13 usable IPs) will be used to provide dedicated IPs for 10 of our clients who require unique SSL certificates for their e-commerce websites. Two IPs will be used for our private nameservers (ns1.examplehosting.com and ns2.examplehosting.com), and the remaining IP will be used by the primary mail service on the server. - **Utilization Plan:** We will assign 8 of the 10 client IPs immediately upon allocation. The two nameserver IPs will also be configured on Day 1. This represents an initial 77% utilization (10/13 IPs). We have 2 new clients scheduled for onboarding within the next 30 days who will require the remaining 2 dedicated IPs, which will bring us to over 92% utilization well within the 90-day requirement.
In IPv4 blocks, three addresses are typically reserved: the Network Address, the Gateway Address, and the Broadcast Address.
Subnet | Total IPs | Usable IPs | Cost Per Month |
---|---|---|---|
/28 | 16 | 13 | $39 |
/27 | 32 | 29 | $87 |
/26 | 64 | 61 | $183 |
/25 | 128 | 125 | $375 |

/21 | 2048 | 2045 | $6,135 |
/20 | 4096 | 4093 | $12,279 |
A /64 is the standard size for a single network and contains an astronomical number of addresses. Larger IPv6 allocations are measured by how many /64 networks they contain.
Subnet | Number of /64 Networks | Cost Per Month |
---|---|---|
/64 (Default) | 1 | Included |
/60 | 16 | $5 |
/56 | 256 | $10 |
/52 | 4,096 | $20 |
