[ruby-core:111591] [Ruby master Feature#19303] Resolv::IPv4::Regex variant without anchors

Issue #19303 has been reported by henk (Hendrik J=E4ger).

Feature #19303: Resolv::IPv4::Regex variant without anchors

https://bugs.ruby-lang.org/issues/19303



* Author: henk (Hendrik J=E4ger)

* Status: Open

* Priority: Normal

----------------------------------------

``` ruby

require 'resolv'

p "match this IP: 10.0.0.1"[/match this IP: (#{Resolv::IPv4::Regex})/, 1]



```



This returns 'nil' because Resolv::IPv4::Regex is anchored with \A and \z.

I would like to have a variant of Resolv::IPv4::Regex available that is not=
 anchored so that code would return '10.0.0.1'.
