ipaddress 1.0.0

CRAN release: 2023-01-12

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 0.5.5

CRAN release: 2022-08-12

Fix for CRAN checks.

ipaddress 0.5.4

CRAN release: 2022-01-11

Fix for CRAN checks.

ipaddress 0.5.3

CRAN release: 2021-07-27

Fix for CRAN checks.

ipaddress 0.5.2

CRAN release: 2021-06-17

• 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

CRAN release: 2020-09-12

• 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

CRAN release: 2020-08-26

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

CRAN release: 2020-08-06

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

CRAN release: 2020-05-12

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().

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

CRAN release: 2020-03-25

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).

• 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.
