Kind: Function

Source: src/utils/ipaddr.ts

Part of: Utils

Expand IPv6 Address

expandIPv6 expands an IPv6 address that uses compressed notation into its expanded colon-separated form. It is used by IP address handling code when later operations need each address segment represented explicitly.

Signature

ts
function expandIPv6(ipV6: string): string

Parameters

Returns: string

console.log(expandedAddress);

AI Coding Instructions

• Pass IPv6 address strings to expandIPv6 before code that requires explicit address segments.
• Keep compressed-address handling inside this utility rather than duplicating expansion logic in callers.
• Preserve colon-separated IPv6 formatting when changing this function.
• Check how callers handle invalid or already-expanded addresses before changing return behavior.
