Rewrite script.js from ES5 (IIFEs, var, .then() chains) to modern ES2022+:
const/let, arrow functions, template literals, async/await, optional
chaining, for...of, .includes(), AbortSignal.timeout(), and DOM APIs
for dynamic HTML construction. Fix unhandled clipboard rejection, abort
timeout leak, and global scope pollution. Update script tag to
type="module" and fix CSS: top -> inset-block-start, flex-start -> start,
and indentation in media query block.
The JS used fragile numeric indices to look up localized labels from the
server-rendered table. When optional rows (ASN, Org, Country, City) were
missing for the primary IP, the indices shifted, causing 'Proxy' to appear
as the City label. Add data-label attributes to each <tr> in the template
and key the label map by name instead of position.
Show a shimmer skeleton placeholder while fetching the local IPv4
address via the IPv4-only domain. When the primary IP is already IPv4,
no loading state is displayed and the alt section fades in directly.
The detectAltIp() function was unconditionally fetching the viewer's own
IPv6/IPv4 address and displaying it alongside queried IP results. Pass
the is_query flag to the client via a data attribute and guard the
alt-IP detection so it only runs when viewing your own IP.
