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.
