Issue #37107 describes problems with IPv6 addresses that contain a zone ID.

The scope of this PR is to ignore the zone ID if any.
This on itself will address the reported bug.

Keep in mind this is the first PR of a series. Subsequent PR will properly read the zone ID and construct IPv6 addresses correctly.

Here's a summary of the code changes

  • change ipStringToBytes to ignore anything after a percent
  • make sure percent does not appear before dot
  • make sure percent does not appear before colon
  • can only contain one percent symbol
  • make sure mixed IPv6IPv4 addresses support zoneId
  • test an address with dots and colons and percent
  • test an address with dots and percents
  • test an address with colons and percents
  • make sure percent does not appear right after dot
  • make sure percent does not appear right after colon

@camilin87 - thanks for the PR. However, until we address the comment here: #37107 (comment) we should hold off on this PR. I am hesitant to proceed with this change in the common library since it touches so much of the code base. In particular, I am concerned about data manipulation (loosing information) when indexed.

I will re-open a discussion about our support (or lack there-of) of zoneId.

I know this issue may need some discussion.
I updated the PR either way in case it adds some clarity.

That being said. I understand if after your discussions this issue is no longer relevant

The updated PR makes sure to read the zone ID

Here's a summary of the changes

  • test non zero zoneIds
    • test it gets read
    • extract a constant for zero
    • make sure it supports hex numbers
  • test the string conversion of non zero zone Id
    • make sure it supports hex numbers
  • fix other failing tests

@camilin87 - We appreciate your contribution here, and have discussed this internally. We landed on implementing an ingest node processor to help handle IPv6 zone_ids. I have logged #38064. I am going to close this PR as we heading a different direction. Feel free to pick up that issue if you like and ping me directly with question or reviews.
