=== USER  (2026-09-11T04:30:00Z) ===
What are the network address, broadcast address, usable host range and number of usable hosts for 10.42.7.130/27?

=== ASSISTANT  (2026-09-11T04:30:00Z, model qwen3.8:latest) ===
usage: prompt_eval_count=10974 eval_count=228 prompt_tokens=10974 completion_tokens=228 total=5.9s prefill=1.6s decode=4.3s 53.2 tok/s

=== [1] THINKING ===
The user is asking about subnet details for 10.42.7.130/27. Let me use the subnet_calc tool.

=== [2] TOOL CALL: subnet_calc  (call_v4neb7ix) ===
{
  "network": "10.42.7.130/27"
}

=== [3] TOOL RESULT: subnet_calc  (call_v4neb7ix) ===
# 10.42.7.128/27

Network address:  10.42.7.128
Broadcast:        10.42.7.159
Netmask:          255.255.255.224  (/27)
Wildcard mask:    0.0.0.31
Total addresses:  32
Usable hosts:     30
Usable range:     10.42.7.129 - 10.42.7.158
Scope:            private (RFC 1918 / ULA)
Reverse DNS zone: 128.7.42.10.in-addr.arpa  [that is the PTR name of the network address itself. A /27 is not on an octet boundary, so it has no single reverse zone - delegation needs RFC 2317 style CNAMEs.]

=== [4] THINKING (0s) ===
The tool has already computed everything. Let me present it clearly.

=== [5] ASSISTANT TEXT ===
For **10.42.7.130/27** (netmask 255.255.255.224):

| Item | Value |
|------|-------|
| **Network address** | 10.42.7.128 |
| **Broadcast address** | 10.42.7.159 |
| **Usable host range** | 10.42.7.129 – 10.42.7.158 |
| **Usable hosts** | 30 |

A /27 gives 32 total addresses (2⁵), minus the network and broadcast addresses = **30 usable hosts**. The address 10.42.7.130 falls within this block, so it's a valid host address (not the network or broadcast). It's in the RFC 1918 private range.
