--- Comment #1 from Mark Thomas <ma...@apache.org> ---
The short answer is because of this text from RFC 1123:
<quote>
However, a valid host name can never have the dotted-decimal form #.#.#.#,
since at least the highest-level component label will be alphabetic.
</quote>

However, there is some interesting discussion of this in the errata. For a full
discussion of how this relates to Tomcat, see the duplicate. The summary of
that discussion is that '-' should be allowed in the final segment and the
parsing has been updated to permit this.
