项目介绍Project Overview

dsh-ipcalc 是 DeepSeek Harness 的 IP 与子网计算插件，提供三个纯本地、零依赖、无网络访问的工具：ipv4_subnet 输出 IPv4 CIDR 的网络号、掩码、广播、主机范围与 IANA 分类；ipv4_summarize 将地址/网段归并为最小覆盖 CIDR；ip_parse 校验并按 RFC 5952 规范化、分类 IPv4/IPv6（含内嵌 IPv4）。适用于需要可靠子网算术、地址归并或地址解析分类时。注意：分类仅覆盖常见 IANA 特殊用途条目，非完整 CIDR 重叠引擎。

dsh-ipcalc is a DeepSeek Harness plugin for IP and subnet math, offering three local, zero-dependency tools with no network I/O. ipv4_subnet returns an IPv4 CIDR's network, netmask, broadcast, host range, counts, and IANA class; ipv4_summarize merges addresses/ranges into the minimal covering CIDR list; ip_parse validates, RFC 5952-normalizes, and classifies IPv4/IPv6 addresses, including embedded IPv4 forms. Use it when agents need reliable subnet arithmetic or address parsing. Caveat: classification covers common IANA registry entries only, not full CIDR-overlap logic.

dsh-ipcalc

IP & subnet math toolbox for DeepSeek Harness (dsh). Three pure-math tools — zero runtime dependencies, no network I/O — so agents stop doing subnet arithmetic in their heads (where they frequently get it wrong).

Tools

Tool What it does
ipv4_subnet Full subnet layout for an IPv4 CIDR: network, broadcast, netmask, wildcard, host range, address counts, integer forms and IANA classes
ipv4_summarize Reduce a list of IPv4 addresses/ranges to the minimal covering CIDR list (merge + supernet)
ip_parse Validate, normalize (RFC 5952) and classify any IPv4/IPv6 address, including embedded IPv4-in-IPv6 forms

Install

dsh plugin --profile <your-profile> add github:TYEclipse/dsh-ipcalc

Usage

ipv4_subnet("192.168.1.25/24")
→ network 192.168.1.0/24
  netmask 255.255.255.0  wildcard 0.0.0.255  broadcast 192.168.1.255
  host range 192.168.1.1 – 192.168.1.254  (254 usable of 256)
  classes: network=private  host=private

ipv4_subnet("10.10.10.10/255.255.255.248")   # dotted-mask input works too
→ network 10.10.10.8/29  (6 usable hosts)

ipv4_summarize(["10.0.0.0/24", "10.0.1.0/24", "10.0.2.0/24", "10.0.3.0/24"])
→ ["10.0.0.0/22"]

ip_parse("::ffff:192.168.1.1")
→ IPv6, class ipv4_mapped, normalized ::ffff:c0a8:101 (embeds 192.168.1.1)

Semantics

  • Exact arithmetic — all math uses plain double arithmetic on 32-bit integers (values up to 2³² are exactly representable), so there is no bitwise-overflow risk.
  • /31 follows RFC 3021 — both addresses are reported as usable (point-to-point links).
  • /32 is a single host — first/last host equal the address itself.
  • Bare addresses are treated as /32; dotted netmasks (/255.255.255.248) are accepted anywhere a prefix length is; non-contiguous masks are rejected.
  • RFC 5952 canonicalization — IPv6 is lowercased, leading zeros stripped, and the longest (leftmost on ties) run of two or more zero hextets compressed to ::.
  • Classification follows the IANA special-purpose registries: IPv4 unspecified / broadcast / loopback / private (10/8, 172.16/12, 192.168/16) / cgnat (100.64/10) / link_local (169.254/16) / documentation (192.0.2/24, 198.51.100/24, 203.0.113/24) / multicast (224/4) / reserved (240/4) / global; IPv6 unspecified / loopback / ipv4_mapped / ipv4_compatible / documentation (2001:db8::/32) / link_local (fe80::/10) / multicast (ff00::/8) / unique_local (fc00::/7) / global. Classification is best-effort for the common registry entries, not a full CIDR-overlap engine.

dsh-ipcalc（中文简介）

面向 DeepSeek Harness 的 IP 与子网数学工具箱，三个纯本地计算工具，零运行时依赖、无任何网络访问：

  • ipv4_subnet：给定 CIDR（支持 a.b.c.d/前缀、点分掩码、裸地址）输出完整子网布局——网络号、广播地址、子网掩码、反掩码、可用主机范围与数量、整数形式、IANA 分类（私网/环回/链路本地/CGNAT/文档段/组播/保留段等）。
  • ipv4_summarize：把一组 IPv4 地址/网段归并成最小覆盖 CIDR 列表（相邻合并 + 对齐超网）。
  • ip_parse：校验、规范化（RFC 5952）并分类任意 IPv4/IPv6 地址，识别 ::ffff:a.b.c.d 内嵌 IPv4 形式。

专门解决大模型心算子网边界常出错的问题；/31 遵循 RFC 3021，/32 视为单主机。
