Networking Tips

LTE public IPs are often pooled. Expect odd cities, shared reputation, and brittle allowlists.

Dynamic WAN addresses are normal. Need inbound stability? Ask for static service, DDNS, or a tunnel.

Wi‑Fi uses the building exit; cellular often uses a shared carrier gateway. Capture each path separately.

Dynamic leases, café Wi‑Fi, cellular, and VPNs mint new public addresses. Recheck before editing allowlists.
