Remove Handling of Leading Zeros in IPv4 Addresses

[bendbennett]

Terraform CLI and Provider Versions

TF v1.2.8
DNS Provider v3.2.3

Use Cases or Problem Statement

As part of maintaining backwards compatibility with pre-1.17 versions of Go that allowed leading zeros in IPv4 address, code changes were made in Return miekg/dns Errors to Practitioners to strip out leading zeros.

Proposal

As part of the next major release we should strip out handling of IPv4 addresses with leading zeros as Go 1.17 and later reject such addresses in ParseIP and ParseCIDR functions.

How much impact is this issue causing?

Low
