Current turn: 2 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Network configurations:
Router 1: 2001:0db8:85a3:0000:0000:8a2e:0370:7334 (primary)
Router 2: 2001:db8:85a3:0:0:8a2e:370:7334 (secondary)
Backup 1: 2001:db8::1428:57ab (failover)
Legacy: 2001:0db8::0001 (archive)
Invalid IPs: 2001:0db8:85a3:0000:0000:8a2e:0370:7334:extra (too many segments)
G2001:db8::370z:7334 (invalid hex character)
2001:db8:0:0:8a2e:370-7334 (invalid separator)
2001db8:85a3::8a2e:370:7334 (missing colon)
::ffff:192.168.0.1 (IPv4-mapped)
fe80::1ff:fe23:4567:890a (invalid - too many segments)
2001:db8:: (valid compressed end)
::1 (loopback)"

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "2001:0db8:85a3:0000:0000:8a2e:0370:7334",
  "2001:db8:85a3:0:0:8a2e:370:7334",
  "2001:db8::1428:57ab",
  "2001:0db8::0001",
  "::ffff:192.168.0.1",
  "2001:db8::",
  "::1"
]

Rules:
1. Your regex must match ALL of the target items in the text.
2. Your regex must NOT match anything else in the text.
3. The pattern should be a valid JavaScript regular expression.
4. Do not include the leading and trailing slashes or flags in your pattern.

You'll use the "make_move" function to submit your solution with:
1. reasoning: Your reasoning for this regex pattern
2. move: The regex pattern as a simple string

Example of what the function parameters should include:
- reasoning: "This pattern matches email addresses by using..."
- move: "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}"

IMPORTANT:
- The regex pattern should be a simple string.
- Do NOT use raw regex notation with slashes like /pattern/.
- Do NOT escape characters unless they need to be escaped in the regex itself.
- For example, to match parentheses, use "\(\)" not "\\(\\)".
- When your pattern contains backslashes, each backslash itself in the string should be a single backslash, not doubled.

Think carefully and test your pattern mentally before submitting.
