Netsome

A Python library for working with common networking types and conversions, including IPv4/IPv6 addresses/networks, MAC addresses, BGP ASNs, VLANs and network interfaces.

Installation

pip install netsome

Features

• IPv4 & IPv6 address and network manipulation (addresses, networks, interfaces)
• IPv6 Support: Full IPv6 address handling with compression, special address types, and IPv4-mapped addresses
• MAC address handling (MAC-48/EUI-48)
• BGP AS number conversions (asplain, asdot, asdotplus formats)
• VLAN ID validation and management
• Network interface name parsing and standardization
• Robust validation for all data types
• Type-safe implementation with proper error handling

Basic Usage

from netsome.types import (
    IPv4Address,
    IPv4Network,
    IPv4Interface,
    IPv6Address,
    IPv6Network,
    IPv6Interface,
    MacAddress,
    ASN,
    VID,
    Community,
    Interface,
)

# IPv4 address and network manipulation
ipv4_addr = IPv4Address("192.168.1.1")
print(ipv4_addr.address)  # "192.168.1.1"
print(ipv4_addr.cidr)  # "192.168.1.1/32"

ipv4_net = IPv4Network("192.168.1.0/24")
print(ipv4_net.prefixlen)  # 24
print(ipv4_net.netaddress)  # "192.168.1.0"

ipv4_interface = IPv4Interface("192.168.1.1/24")
print(ipv4_interface.address)  # "192.168.1.1"
print(ipv4_interface.network)  # "192.168.1.0/24"

# IPv6 address and network manipulation
ipv6_addr = IPv6Address("2001:db8::1")
print(ipv6_addr.address)  # "2001:db8::1"
print(ipv6_addr.expanded)  # "2001:0db8:0000:0000:0000:0000:0000:0001"
print(ipv6_addr.is_global)  # True

ipv6_net = IPv6Network("2001:db8::/32")
print(ipv6_net.prefixlen)  # 32
print(len(list(ipv6_net.subnets(prefixlen=64))))  # 4294967296

ipv6_interface = IPv6Interface("2001:db8::1/64")
print(ipv6_interface.address)  # "2001:db8::1"
print(ipv6_interface.network)  # "2001:db8::/64"

# IPv6 special address detection
link_local = IPv6Address("fe80::1")
print(link_local.is_link_local)  # True

multicast = IPv6Address("ff02::1")
print(multicast.is_multicast)  # True

# Work with MAC addresses
mac = MacAddress("001122334455")
print(mac.is_unicast())  # True
print(mac.oui)  # "001122"

# Handle BGP AS numbers
asn = ASN.from_asdot("64512.1")
print(asn.to_asplain())  # "4244897793"

# Work with BGP Communities
community = Community.from_str("65000:100")
print(str(community))  # "65000:100"
print(int(community))  # 4259840100

# Manage VLAN IDs
vid = VID(100)
print(vid.is_reserved())  # False

# Parse and work with network interface names
iface = Interface("eth0")
print(iface.type)  # IFACE_TYPES.ETHERNET
print(iface.value)  # "0"
print(iface.canonical_name)  # "Ethernet0"
print(iface.abbreviated_name)  # "Eth0"
