IPv4 Block Sizes and Prices
IPv4 blocks are written in CIDR notation (/29, /24 and so on). Three addresses in a block are reserved for the network address, the broadcast address and the gateway, so the number of usable IPs is the total minus 3.
| Plan | Block | Total addresses | Usable IPs | RDNS | WHOIS record | Monthly |
|---|---|---|---|---|---|---|
| SNCIP-1 | /29 | 8 | 5 | Yes | No | |
| SNCIP-2 | /28 | 16 | 13 | Yes | No | |
| SNCIP-3 | /27 | 32 | 29 | Yes | No | |
| SNCIP-4 | /26 | 64 | 61 | Yes | No | |
| SNCIP-5 | /25 | 128 | 125 | Yes | No | |
| SNCIP-6 | /24 | 256 | 253 | Yes | Yes | |
| SNCIP-7 | /22 | 1,024 | 1,022 | Yes | Yes |
Prices are the monthly amount on the plan cards converted at the current exchange rate. For /24 and /22 blocks the WHOIS record can be registered in your name; smaller blocks do not support a WHOIS record. Reverse DNS (RDNS) can be set on every block.
Which IPv4 Block Fits You?
/29 – /27
Enough for separate IPs for a few websites, a clean IP for an SSL or mail server, or a small VPN or proxy setup.
/26 – /25
Suits infrastructures with many virtual servers, hosting companies and agencies giving clients their own IPs.
/24 and /22
The smallest block that can usually be announced over BGP from your own ASN is a /24. The right choice for companies that need a WHOIS record and announce their own network.
