When you obfuscate

 "obfuscate 10.0.129.220 and 10-0-129-220"

The result is  "obfuscate x-ipv4-000001-x and x-ipv4-000002-x", whereas this should actually be the same replacement. That happens frequently with folder names and their corresponding log file contents.

quick testcase to repro:

{
	name:   "standard ipv4 and standard ipv4 should map to same ip",
	input:  []string{"obfuscate 10.0.129.220 and 10-0-129-220"},
	output: []string{"obfuscate x-ipv4-000001-x and x-ipv4-000001-x"},
	report: map[string]string{
		"10.0.129.220": "x-ipv4-000001-x",
	},
},

AC:

• The same IP should be mapped to the same replacement, regardless of their initial formatting
• additional unit testing
• including the above case for the IP obfuscator as a regression test
