ifpretty

Prettify and enrich ifconfig output — aligned tables, color, decoded flags, IP/MAC/scope annotations, OUI vendor lookup, live DNS/DHCP/route, and a 1‑hour bandwidth graph. Built on rich; macOS‑focused.

ifconfig | ifpretty

Install

pip install ifpretty

Usage

ifpretty                       # essentials view; runs `ifconfig` for you
ifpretty -v                    # verbose: every field + expand collapsed interfaces
ifpretty en0                   # limit to one or more interfaces
ifconfig | ifpretty            # or pipe ifconfig in yourself
ifconfig | ifpretty --records  # compact label/value record layout
ifconfig | ifpretty --table    # single wide table, all fields as columns (<=240)
ifconfig | ifpretty --live      # + route, traffic, friendly names, DNS, DHCP (macOS)
ifconfig | ifpretty --check     # + ping the default gateway for latency (macOS)
ifconfig | ifpretty --wan       # + public IP / ASN / geo (opt-in; sends IP to ipapi.co)
ifpretty --diff                 # show what changed since the previous run
ifconfig | ifpretty --explain   # append a legend explaining the flags/options seen
ifpretty --update-oui           # refresh the bundled IEEE vendor database

Run it bare and it runs ifconfig for you; or pipe ifconfig in to control which interfaces to show. The default is an essentials view (identity, routable IPs, gateway, throughput) that collapses down/address-less interfaces to one line; pass -v for every field.

What it adds

Always on (offline, deterministic):

• Per‑interface role (loopback / Ethernet·Wi‑Fi / VPN·tunnel / bridge / …).
• IP scope for every address — loopback / link‑local / ULA / private / global — plus IPv4 network + usable‑host count.
• MAC kind (universal vs locally‑administered), OUI vendor (bundled IEEE registry, no network), shared‑MAC notes (e.g. bridge members), and EUI‑64 detection.
• Media speed/duplex with a half‑duplex ⚠ warning; jumbo / sub‑1280 MTU notes.
• Decoded flag/option/nd6 bitfields; aligned IPv6 attribute columns.

--live (macOS, cross‑references the system):

• Default route + gateway, friendly hardware‑port names, per‑interface DNS and search domains, DHCP server + lease, traffic counters (bytes + packets) and error/collision counts.

--check: pings the default gateway and reports latency.

--wan (external, opt‑in): looks up your public IP plus ASN/ISP/geo via ipapi.co and shows it in the overview. This sends your public IP to a third party, so it is strictly opt‑in; the result is cached for ~1 h, times out fast, and degrades silently offline. --update-oui refreshes the vendor database from the IEEE registry into ~/.cache/ifpretty/ (overrides the bundled copy).

--diff: every run records a snapshot of the stable interface state (up/down, addresses, MAC, mtu, media, gateway — not volatile counters) to ~/.cache/ifpretty/snapshot.json. With --diff, ifpretty prints what changed since the previous run — interfaces added/removed, status flips, and added/removed IPv4/IPv6 addresses — before the normal view.

1‑hour bandwidth graph: schedule the recorder, then a Unicode sparkline of the last hour appears automatically:

# once, e.g. in crontab -e
* * * * * /usr/local/bin/ifpretty --record

1h in  ▁▁▁▂▄█▅▂▁▁▁▁   peak 10.0 Mbps
1h out ▁▂▂▄▆█▄▂▂▁▁▁   peak 533.3 Kbps

History is stored at ~/.cache/ifpretty/samples.csv (override with IFPRETTY_HISTORY).

Notes

• Colors auto‑disable when piped; force with CLICOLOR_FORCE=1, disable with NO_COLOR=1.
• --live / --check / --record use macOS tools (route, netstat, networksetup, scutil, ipconfig, ping) and no‑op elsewhere.
