What factor does NOT contribute to web server naming issues?

Overlapping network routes do not directly contribute to web server naming issues. Naming issues typically arise from factors that affect how servers are identified and accessed via domain names or virtual hosts. When users or systems attempt to resolve a domain name, they rely on defined host configurations, and if these are not correctly set up, issues can occur.

Undefined virtual host names can lead to confusion about which server configuration should handle a request, while localhost configurations can complicate access to servers due to potential mismatches between the specified domain name and the internal server address. Multiple domain-linked IP addresses can create ambiguity if the DNS or server settings do not clarify which domain corresponds to which IP address.

In contrast, overlapping network routes primarily deal with how data packets are transmitted across networks, independent of how names are resolved or how hosts are identified. Therefore, this aspect does not have a direct impact on naming issues related to web server configurations.
