What it does
Subnet Calculator is an agent skill from automateyournetwork/netclaw. IPv4 and IPv6 subnet calculator - CIDR breakdown, usable hosts, previous/next subnets, address classification, VLSM planning, and dual-stack analysis. Use when calculating subnets, figuring out how many hosts fit in a prefix, planning IP addressing, getting wildcard masks for ACLs, or checking if two IPs are in the same subnet.
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: An AI agent that claws through your network. The licence is Apache-2.0.
When your agent uses it
- Calculating subnets
- Figuring out how many hosts fit in a prefix
- Planning IP addressing
- Getting wildcard masks for ACLs
Example prompts
- “/subnet-calculator”
Requirements
- Python 3
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit aa90e7d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Subnet Calculator loads about 2.3k tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 539 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Subnet Calculator (IPv4 + IPv6)
Available Tools
1. subnet_calculator — IPv4 Subnet Details
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator '{"cidr":"192.168.1.0/24"}'Parameters:

Returns:
- Network address, broadcast address, netmask, wildcard mask
- Prefix length, host bits
- Number of total and usable addresses
- First and last usable host addresses

- Address classification: private, global, link-local, multicast, loopback, reserved
- Human-readable summary
2. subnet_calculator_v6 — IPv6 Subnet Details
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator_v6 '{"cidr":"2001:db8::/48"}'Parameters:
cidr(required): IPv6 CIDR notation, e.g.,2001:db8::/32,fd00::/64,fe80::/10
Returns:
- Network address (compressed and exploded forms)
- Last address in range

- Human-readable summary
3. subnet_calculator_auto — Auto-Detect IPv4/IPv6
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator_auto '{"cidr":"10.0.0.0/24"}'
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator_auto '{"cidr":"2001:db8:abcd::/48"}'Automatically detects IP version and calls the appropriate calculator.
When to Use
- Interface addressing: Calculate the correct subnet for a new interface
- VLSM planning: Break a large block into appropriately sized subnets
- ACL wildcard masks: Get the wildcard mask for access-list entries
- Routing verification: Confirm that route entries match expected subnets
- IPv6 migration planning: Understand IPv6 allocation standards (/48, /64, /128)
- Network design: Validate addressing schemes before deployment
- Troubleshooting: Verify if two IPs are in the same subnet
Common Network Engineering Scenarios
Scenario 1: Point-to-Point Link Addressing
IPv4 /30 link:
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator '{"cidr":"10.1.1.0/30"}'Result: 4 addresses, 2 usable (10.1.1.1 and 10.1.1.2). Standard for router-to-router links.
IPv4 /31 link (RFC 3021):
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator '{"cidr":"10.1.1.0/31"}'Result: 2 addresses (10.1.1.0 and 10.1.1.1). No broadcast waste.
IPv6 /127 link (RFC 6164):
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator_v6 '{"cidr":"2001:db8:1::/127"}'Result: 2 addresses. Recommended for IPv6 point-to-point links.
Scenario 2: VLSM Subnet Planning
Break 10.10.0.0/16 into subnets for different departments:
# Engineering: 500 hosts needed → /23 (510 usable)
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator '{"cidr":"10.10.0.0/23"}'
# Sales: 100 hosts needed → /25 (126 usable)
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator '{"cidr":"10.10.2.0/25"}'
# Management: 10 hosts needed → /28 (14 usable)
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator '{"cidr":"10.10.2.128/28"}'
# Server VLAN: 30 hosts needed → /27 (30 usable)
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator '{"cidr":"10.10.2.192/27"}'Produce an addressing plan:

Integration with Network Config
After calculating subnets, use pyats-config-mgmt to apply:
# Calculate the subnet first
python3 $MCP_CALL "python3 -u $SUBNET_MCP_SCRIPT" subnet_calculator '{"cidr":"10.1.1.0/30"}'
# Then configure the interface
PYATS_TESTBED_PATH=$PYATS_TESTBED_PATH python3 $MCP_CALL "${PYATS_PYTHON:-python3} -u $PYATS_MCP_SCRIPT" pyats_configure_device '{"device_name":"R1","config_commands":["interface GigabitEthernet2","ip address 10.1.1.1 255.255.255.252","no shutdown"]}'Failure Behavior
- If a tool call fails with an authentication or connection error, check that
MCP_CALL,PYATS_MCP_SCRIPT,SUBNET_MCP_SCRIPTare set and valid before assuming a data or device problem. - On a tool error (timeout, unreachable host, malformed response), report the failure and its error message directly to the user rather than fabricating or guessing at results.
- For a confirmed read-only call, check connectivity and retry once if appropriate. For any call that changes state or sends a message, a timeout does not prove the action failed: inspect current state or delivery status before retrying, preserve the required approval/change gates, and do not repeat an action whose outcome is unknown.

Can I use Subnet Calculator in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add automateyournetwork/netclaw --skill subnet-calculator -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/subnet-calculator, .gemini/skills/subnet-calculator, .github/skills/subnet-calculator and .opencode/skills/subnet-calculator in your project.
What does Subnet Calculator need to run?
Going by SKILL.md and its folder, Subnet Calculator needs the command-line tools its instructions call (python3). Our summary lists: Python 3.
Does Subnet Calculator access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
