updates.checkpoint.com IPv6 problems

Hello Community,

is anyone aware of the IPv6 DNS problem, updates.checkpoint.com suffers since a few days?

This is really annoying because it's makes our automatic updates (for IPS e.g) unreliable in an Dual Stack environment.

Details:

Do a query to a DNS resolver of your choice and ask for an A record and for an AAAA record for updates.checkpoint.com.

When asking for an A record, you will always get an answer (and you will get the answer fast). The answer will be the CNAME updates.g01.checkpoint.com and almost all resolvers will provide you the A record for this CNAME in the same answer.

When asking for an AAAA record, you will sometimes get an answer and sometimes not. The answer (if you get any) will be the CNAME updates.g01.checkpoint.com and almost all resolvers will provide you the AAAA record for this CNAME in the same answer. If it is not working, depending on the current cache status of the resolver you asked, it can take a quite long time before you get the SERVFAIL answer. So there are three options for an IPv6 DNS query:

  • Correct answer (you will get an AAAA record in the end)
  • Wrong answer immediatly (you will get an NXDOMAIN from your resolvers cache)
  • Wrong answer after a long waittime (in my cases sometimes more than the 20sec my dig was waiting)

I've tried this not only with our own resolvers, but also with the public ones from Level 3 (4.2.2.1) and Google (8.8.8.8). Doing this, I can say this is not a problem on our side.

Please see the following tests I did today (timestamps included). You will see sometimes it is working, sometimes not.

Last year, User Center was not reachable over IPv6 for quite a long time. We created a TAC case and they got it fixed after a few days. We were wondering that they did not detect this thereself. I thought Dual Stack should be quite common these times.

Checkpoint team, are you aware of this new IPv6 DNS problem for your subdomain?

Re: updates.checkpoint.com IPv6 problems

I've been told this should be fixed now.
If you're still having an issue, let me know.

Re: updates.checkpoint.com IPv6 problems

That was fast, thank you!

I can confirm that the DNS problem is now fixed.

However, I have still problems with updates.checkpoint.com in Dual Stack environments, but this time, its not a DNS problem.

This time, I will not get an answer from updates.checkpoint.com when trying to connect with IPv6. I get answers using IPv4 without problems. I tried to connect to an IPv6-only google server and this is working fine so I'm pretty sure again, that the problem is not on my side.

Please see my tests:
