Quick answer

ip neigh helps authorized labs sample neighbor/ARP table show/get literacy on hosts they own. Pair with ip-route-tips, ip-addr-tips, ss-tips, traceroute-tips, ip-netns-tips. Prefer lab VMs — never poison foreign neighbor tables without permission. Distinct from ip-route-tips.

Tip checklist (authorized only)

  1. Confirm you may run ip neigh on the lab host (syllabus box you own; some mutations need root/CAP).
  2. Prefer documenting who / why / ticket before any neighbor mutation — never change production neighbor entries without change control.
  3. Record short factual notes; quote short Evidence (IP + MAC + device — never secrets).
  4. Optional: route peer → ip-route-tips.
  5. Optional: address peer → ip-addr-tips.
  6. Prefer disposable lab VMs and throwaway namespaces for neigh drills; quote non-secret labels afterward as Evidence.
  7. Prefer ip neigh show / ip neigh get <ip> read-back before and after authorized changes — refuse unauthorized ARP-poison cookbooks.
  8. Stop at literacy — no attack or unauthorized neighbor-bypass cookbooks.

Allowed framing

  • Classroom labs reviewing ip neigh show / ip neigh get <lab-ip> on authorized disposable hosts.
  • Binding short factual notes as Evidence (IP + MAC + device — no secrets).
  • Documenting expected vs observed neighbor rows for authorized notes.
  • Comparing ip-neigh ↔ ip-route / ip-addr / ss / traceroute / ip-netns peer tip pages under one binder.
  • Testing syllabus-approved lab-net neigh add/del only when change control authorizes that drill on lab resources.

Scope we will not cover

  • No crack/pirate/keygen via ip neigh.
  • No intentional unauthorized ARP poison / neighbor injection against foreign hosts.
  • No secret-theft or MAC harvesting framed as attack against hosts you do not own.
  • No cookbooks that use neighbor tables as an attack step against production without authorization.
  • No ip neigh framed as a network-bypass against systems you do not own.

Beginner path (authorized only)

  1. Obtain one syllabus-approved disposable lab host with iproute2 available.
  2. Prefer a throwaway lab VM (or ip-netns-tips namespace) before any neigh-mutation drill.
  3. With authorization, run ip neigh show then ip neigh get <lab-ip>; quote selected IP/MAC/device labels as Evidence.
  4. Optional: peer tip pages above when the syllabus asks.
  5. Stop at literacy — no attack or unauthorized ARP-poison cookbooks.

Practical notes for authorized labs

  • ip neigh shows the neighbor/ARP cache — keep Evidence labels distinct from ip-route-tips FIB rows.
  • Pair with ip-addr-tips when the syllabus zooms on link identity beside neighbor rows.
  • ip neigh get is a great read-only drill — document selected IP/MAC/dev without dumping unrelated privileged state.
  • Prefer documenting IP / MAC / device labels the syllabus authorized.
  • Never commit neigh dumps with secrets or proprietary host inventories to git — even for labs.

FAQ-aligned refusals (quick)

  • Foreign-host ARP poison → refuse.
  • Unauthorized neighbor-bypass / hostile-injection attack cookbooks → refuse.
  • Attack/credential-theft framing → refuse.
Which to pick
  • Prefer authorized, redacted, secret-free Evidence.
  • Use ip-route / ip-addr / ss / traceroute / ip-netns peer tip pages when the syllabus asks.
  • No crack or unauthorized-access framing.

FAQ

What is an "ip neigh tip" page in BinBench framing?

A checklist for authorized neighbor/ARP-table Evidence (ip neigh show / ip neigh get on lab hosts) on hosts you own or were given syllabus access to — not a cookbook for poisoning foreign neighbor tables without permission.

How does this relate to ip-route-tips / ip-addr-tips / ss-tips / traceroute-tips / ip-netns-tips?

ip-route-tips covers routing tables; ip-addr-tips covers address/link identity; ss-tips covers sockets; traceroute-tips covers path hops; ip-netns-tips covers namespaces. This page zooms on an ip neigh tip checklist — it does not overwrite those pages.

Can I run ip neigh against hosts I do not own?

No. Authorization first. BinBench will not publish unauthorized neighbor-table drills against foreign hosts.

Does this teach attack or ARP-poison / neighbor-bypass PoCs via ip neigh?

No. Mentions of attack/bypass/poison appear only as refusals. Authorized literacy only — prefer lab VMs and redacted IP/MAC labels. Never teach hostile neighbor injection as an attack step.

Does this teach secret theft via ip neigh?

No. Never paste neighbor dumps with secrets, foreign host inventories, or credential-bearing tunnel keys into notes. Prefer documenting IP / MAC / device labels only.
