ARP(3)

💖 ARP(3) — the arp module, bestie edition 💖

okay so this is the manual page for packet.internet.arp, which ships in arp 1.0 — and no, it's not about the little noise your fridge makes, it's about networking. Pull up a chair. 🪑✨

🌸 NAME 🌸

packet.internet.arp — the ARP module. that's it, that's the name. iconic behavior honestly.

---

🦋 DESCRIPTION 🦋

It decodes ARP and RARP layers. that's the whole job. she does it beautifully. 💅

the receipts, aka the actual RFCs:

• RFC 826 — An Ethernet Address Resolution Protocol
• RFC 903 — A Reverse Address Resolution Protocol

✨ CLASSES ✨

👑 class ARP(baseobj.BaseObj)

the ARP object. main character energy fr fr.

Usage:

from packet.internet.arp import ARP

x = ARP(pktt)

Object definition:

ARP(
    htype = int,    # Hardware type
    ptype = int,    # Protocol type
    hlen  = int,    # Byte length for each hardware address
    plen  = int,    # Byte length for each protocol address
    oper  = int,    # Opcode
    sha   = string, # Hardware address of sender of this packet
    spa   = string, # Protocol address of sender of this packet
    tha   = string, # Hardware address of target of this packet
    tpa   = string, # Protocol address of target of this packet
)

🎀 Methods defined here:

---------------------

__init__(self, pktt)

Constructor bestie!! she's initializing the object's private data. that's the vibe.

• pktt: the Packet trace object (packet.pktt.Pktt), so this layer has access to the parent layers. yes she needs to know who her parents are, we all do 💀

---

🌈 class RARP(ARP)

ARP object — but reverse. same energy, opposite direction 🦋

Usage:

from packet.internet.arp import ARP

x = ARP(pktt)

Object definition:

ARP(
    htype = int,    # Hardware type
    ptype = int,    # Protocol type
    hlen  = int,    # Byte length for each hardware address
    plen  = int,    # Byte length for each protocol address
    oper  = int,    # Opcode
    sha   = string, # Hardware address of sender of this packet
    spa   = string, # Protocol address of sender of this packet
    tha   = string, # Hardware address of target of this packet
    tpa   = string, # Protocol address of target of this packet
)

💜 class arp_oper(packet.utils.Enum)

enum arp_oper. she's an enum. she contains multitudes (well, opcodes) ⭐
