Cloudflare DNS Incorrect Name Resolution lastpass.com

Hello,

I am using Cloudflare DNS (1.1.1.1) and I noticed an SSL certificate error when attempting to reach lastpass.com. The SSL was for *zomans.com, part of zomato.com a different corporate website causing an issue with Chrome trusting the cert. Rather than an explicit attack I believe this may be isolated to the DNS service itself. All other devices not on cloudflare DNS resolve lastpass correctly.

This is the current IP returned from DNS: 184.30.167.188
which resolves to Akamai at a184-30-167-188.deploy.static.akamaitechnologies.com

Other DNS providers resolve lastpass.com to the correct IP: 104.70.192.226

So the problem is probably with Cloudflare DNS at 1.1.1.1. I just want it noted and investigated.

Hi, this name is on Akamai CDN so it returns a variety of addresses depending on the location of the closest cache. I haven’t seen 184.30.167.188 returned in any of the logs for lastpass.com or any of its subdomain. Can you add a traceroute and capture some debug information to make sure you’re connected to 1.1.1.1? Have problems with 1.1.1.1? *Read Me First*

Result of tracert. I most definitely have my router configured for 1.1.1.1 and 1.0.0.1 for static DNS resolution but I have it connected to a secondary modem with routing capabilities (disabled) from the ISP.

Edit: I thought I had included 1.0.0.1 but I had not. Still having issue.

Hi, sorry I meant a traceroute to 1.1.1.1, also running the queries from Have problems with 1.1.1.1? *Read Me First* to check that you’re actually connected to 1.1.1.1.
