v2.0.1 (Mar 29, 2021)

IMPORTANT: Security Fix

This version contains an important security fix. If you are using netmask <=2.0.0, please upgrade to 2.0.1 or above.

• Rewrite byte parsing without using JS parseInt()(commit)
  • This is CVE-2021-29418.

Bugfixes

• Add checks on spaces before and after bytes
  • This will now throw an exception when spaces are present like ' 1.2.3.4' or '1. 2.3.4' or '1.2.3.4 '.

Internal Changes

• Avoid some useless memory allocations
• New Mocha testing suite, thanks @kaoudis #36

v2.0.0 (Mar 19, 2021)

Breaking Change

Previous API was treating IPs with less than for bytes as IP with a netmask of the size of the provided bytes (1=8, 2=16, 3=24) and was interpreting the IP as if it was completed with 0s on the right side.

Proper IP parsing for these is to consider missing bytes as being 0s on the left side.

Mask size is no longer infered by the number of bytes provided.

This means that the input 216.240 will no longer be interpreted as 216.240.0.0/16, but as 0.0.216.240/32, as per convention.

See the change.

Bugfixes

• Fix improper parsing of hex bytes
