ipaddress 0.4.0

New features

• Add support for constructing ip_network() vectors without using CIDR notation
  • New common_network() function finds the smallest network containing two addresses
  • New summarize_address_range() function lists the constituent networks of an address range
  • prefix_length() can now infer the prefix length from an ip_address() vector of netmasks and/or hostmasks. This makes it possible to construct an ip_network() vector like so:
    • ip_network(ip_address("192.0.2.0"), prefix_length(ip_address("255.255.255.0")))
    • ip_network(ip_address("192.0.2.0"), prefix_length(ip_address("0.0.0.255")))
• New supernet() and subnets() functions for traversing the network hierarchy
• Added vignette("ipaddress-examples") to describe some typical usage patterns

Minor improvements and fixes

• Check for user interrupts when processing large data sets
• integer_to_ip() now accepts integerish doubles
• Addition/subtraction operators now accept integerish doubles
• Addition/subtraction operators now catch missing values in 2nd argument
• netmask() and hostmask() now raise an error if the prefix_length and is_ipv6 arguments are not both specified
• Fix is_within_any() to correctly catch when IPv6 addresses are in zero networks
• Rename vignette("ipaddress") as vignette("ipaddress-classes")

ipaddress 0.3.0

Breaking changes

• Renamed functions for converting to and from alternative representations of IP addresses:
  • as_packed() and from_packed() become ip_to_bytes() and bytes_to_ip()
  • as_binary() and from_binary() become ip_to_binary() and binary_to_ip()
  • as_hostname() and from_hostname() become ip_to_hostname() and hostname_to_ip()

New features

• New ip_to_integer() and integer_to_ip() functions to encode and decode addresses as integers. Note that the integers are contained within a character vector. Please see the function documentation for an explanation.

Minor improvements

• Support pretty printing in tibbles
  • CIDRs aligned on forward slash separator
  • Prefix length displayed in green to increase prominence
  • Dots and colons displayed in gray to reduce prominence
  • IPv6 addresses can be automatically truncated, to fit more columns into the console width
• Added hex logo
• Compatible with vctrs 0.3.0

ipaddress 0.2.0

Classes

• Added vignette("ipaddress") to introduce the data classes provided by ipaddress
• New ip_interface() class to simultaneously store the address and the network it is on
• ip_address() vectors now support bitwise operations (!, &, | and ^)
• ip_address() vectors now support addition and subtraction of integers
• Added an ip_network() constructor that accepts ip_address and prefix length vectors

Other representations

• New as_packed() and from_packed() functions to encode and decode addresses as raw bytes
• New as_binary() and from_binary() functions to encode and decode addresses as binary strings
• New as_hostname() and from_hostname() functions translate addresses to and from hostnames

Address space

• New max_prefix_length() function to get the size of the address space (32-bit for IPv4 and 128-bit for IPv6)
• New functions to check if addresses or networks are reserved for special use: is_multicast(), is_unspecified(), is_loopback(), is_link_local()
• New functions for IPv6 transition mechanisms:
  • is_ipv4_mapped(), is_6to4(), is_teredo()
  • extract_ipv4_mapped(), extract_6to4(), extract_teredo_server(), extract_teredo_client()

Network membership

• New functions about the size of a network: num_addresses(), network_address() and broadcast_address()
• New overlaps() function to check for any overlap between networks
• netmask() and hostmask() are now generics, so they can now accept:
  • an ip_network() vector (existing behavior)
  • an ip_interface() vector
  • a vector of prefix lengths

Generating addresses

• New seq.ip_network() and hosts() functions to list all addresses within a network
• New functions to randomly sample addresses: sample_ipv4(), sample_ipv6() and sample_network()

Miscellaneous improvements

• Improved input validation warnings. They now report the row number involved and no longer mention internal function names.
• Many functions now support tidy vector recyling
• Performance improvements

ipaddress 0.1.2

• Fixed decoding bug which meant that some IP addresses were interpreted as NA
  • In IPv4, this affected 0.0.0.128
  • In IPv6, this affected any address in the 0:80::/32 network
• is_subnet() and is_supernet() now check the prefix length, to ensure they are a true subnet or supernet.

ipaddress 0.1.1

Hotfix for CRAN errors on Solaris.

ipaddress 0.1.0

First CRAN release

• Added ip_address() and ip_network() classes
  • Full support for both IPv4 and IPv6 address spaces
  • Efficiently store data in their native representations (i.e. a sequence of bits)
  • Classes based on vctrs package for full tidyverse compatibility
• Added functions to determine network membership
  • is_within() and is_within_any() check if addresses are within networks
  • is_subnet() and is_supernet() check if networks are within other networks
• Added convenience functions to extract IP metadata
  • is_ipv4() and is_ipv6() classify the address space
  • prefix_length(), netmask() and hostmask() yield different representations of the network mask
• Calculations performed in C++ (using Rcpp and AsioHeaders packages) for improved performance
