ipaddress 1.0.2

Fix for CRAN checks.

ipaddress 1.0.1

Fix for CRAN checks.

ipaddress 1.0.0

To mark the release of ipaddress 1.0.0, some breaking changes were made to improve the interface for data analysis.

Breaking changes

• Removed the multiple argument from ip_to_hostname() and hostname_to_ip() (#83).
  • ip_to_hostname() and hostname_to_ip() now always return one result per input (stored in a vector).
  • New ip_to_hostname_all() and hostname_to_ip_all() return all results per input (stored in a list of vectors).
• subnets() now takes vector input and outputs a list of vectors (#83).
• Some arguments must now be explicitly passed using the argument name:
  • The strict argument of ip_network().
  • The exploded argument of format.ip_address(), format.ip_network() and format.ip_interface().
  • The replace argument of sample_ipv4(), sample_ipv6() and sample_network().

New features

• New country_networks() downloads IP networks registered to specific countries (#87).
• Error formatting has been improved using {cli} (#86).

Minor improvements and fixes

• The is_ipv6 argument of netmask() and hostmask() defaults to NULL. This option prefers an IPv4 mask, but creates an IPv6 mask as a fallback.
• Renamed vignette("ipaddress-classes") to vignette("ip-data").
• Renamed vignette("ipaddress-examples") to vignette("recipes").
• Updated the iana_ipv4 dataset.
• Tests now use {testthat} 3e.

ipaddress 0.5.6

Fix for CRAN checks.

ipaddress 0.5.5

Fix for CRAN checks.

ipaddress 0.5.4

Fix for CRAN checks.

ipaddress 0.5.3

Fix for CRAN checks.

ipaddress 0.5.2

• The base argument of ip_to_integer() is removed.
  • base = "dec" is still handled by ip_to_integer().
  • base = "bin" is still handled by the existing ip_to_binary() function.
  • base = "hex" is now handled by the new ip_to_hex() function.
• ip_to_integer() and integer_to_ip() now use bignum::biginteger() vectors to store IP addresses as integers. Previously, these integers were stored in a character vector (because they were beyond the range of base R numeric types).
  • The BH package is no longer a dependency (C++ Boost headers were a heavy dependency).
  • The bignum package is now an optional dependency.
• New ip_to_hex() and hex_to_ip() functions to encode and decode addresses as hexadecimal strings.

ipaddress 0.5.1

• Addition/subtraction of large integers is now much faster (#64).
• ip_to_bytes() now returns a list of raw vectors instead of a blob object (#65).
  • Result can still be converted using blob::as_blob().
  • Removes excessive blob package dependency.
• Refactored C++ code to reduce dependence on Asio library (#64).
  • Package developers can now use LinkingTo: ipaddress without LinkingTo: AsioHeaders.

ipaddress 0.5.0

This release achieves feature parity with the Python ipaddress module (#46).

New features

• Additional checks for reserved addresses/networks: is_private(), is_reserved(), is_site_local() (#49).
• New is_global() checks if addresses or networks are not reserved (#49).
• New collapse_networks() collapses contiguous and overlapping networks (#54).
• New exclude_networks() removes networks from others (#59).
• New reverse_pointer() returns the record used by reverse DNS (#57).
• New datasets: iana_ipv4 and iana_ipv6 contain registries of allocated blocks (#55).
• New bitwise shift operators: %<<% and %>>% (#52).
• Reorganized C++ code to expose IpAddressVector and IpNetworkVector classes to other packages (use LinkingTo: AsioHeaders, ipaddress, Rcpp). This does not affect the public R interface (#51).

Minor improvements and fixes

• format.ip_address(), format.ip_network() and format.ip_interface() gain an exploded parameter to display leading zeros for IPv6 addresses (#56).
• ip_to_integer() gains a base parameter to select between decimal, hexadecimal and binary outputs (#47).
• Integer-like doubles are now accepted everywhere in place of an integer.
• Update vignette("ipaddress-examples") to use the fuzzyjoin package (#61).
• Update vignette("ipaddress-examples") with how to randomly generate public IP addresses (#62).
• Fixed comparison of ip_address() vectors to account for machine endianness (#53).
• Comparison of ip_network() and ip_interface() vectors is now consistent with the Python ipaddress module.
  • ip_network(): network address compared before prefix length.
  • ip_interface(): network compared before host address.

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 (#39).
  • New summarize_address_range() function lists the constituent networks of an address range (#41).
  • 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: (#36)
    • 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 (#42).
• Added vignette("ipaddress-examples") to describe some typical usage patterns (#43).

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 (#38).
• 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: (#30)
  • 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 (#30).

Minor improvements

• Support pretty printing in tibbles (#27).
  • 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 (#31, #34).

ipaddress 0.2.0

Classes

• Added vignette("ipaddress") to introduce the data classes provided by ipaddress (#24).
• New ip_interface() class to simultaneously store the address and the network it is on (#15).
• ip_address() vectors now support bitwise operations (!, &, | and ^).
• ip_address() vectors now support addition and subtraction of integers (#14).
• Added an ip_network() constructor that accepts ip_address and prefix length vectors (#9).

Other representations

• New as_packed() and from_packed() functions to encode and decode addresses as raw bytes (#13).
• New as_binary() and from_binary() functions to encode and decode addresses as binary strings (#18).
• New as_hostname() and from_hostname() functions translate addresses to and from hostnames (#22).

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: (#16)
  • 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() (#11, #19).

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

Fix for CRAN checks.

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.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
