@AnandChowdhary Thank you, but unfortunately your code rewrite broke our original PR 😦

You can see your code here

uptime-monitor/src/update.ts

Lines 160 to 170 in 1999eda

	if (isIP(url)) {
	if (site.ipv6 && !isIPv6(url))
	throw new Error("Site URL must be IPv6 for ipv6 check");
	else if (site.ipv6)
	address = (await dns.promises.resolve6(url))[0];
	else
	address = (await dns.promises.resolve4(url))[0];
	if (isIP(url) && !isIP(address))
	throw new Error("Site IP address could not be resolved");
	}

vs our original PR fcebd9e#diff-0dd1092b99d3bb57c98957de5ec7d4f502b3470e49f3442d152980e40deb0a60R161-R173.

We've submitted another PR to resolve this, can you please merge and release to npm?

Thank you 🙏
