Too Many DNS Lookups | Email Deliverability Problems with SPF Records

Posted on 12/15/2023 By firstdns

An issue often associated with managing SPF records is something called ‘Too many DNS lookups’. When the number of DNS queries from your SPF record crosses the 10 lookup limit, the email receivers could skip those lookup terms. This could cause an SPF fail. As a result, the emails sent on your behalf have a … Read More “Too Many DNS Lookups | Email Deliverability Problems with SPF Records” »

I’ve got an Azure static web app and I’m trying to add a custom domain for my website. My DNS management is through Cloudflare and usually, I do a CNAME validation (add a CNAME record in Cloudflare pointing to my static web app) and validate the same thing from the Azure side. ​ In my … Read More “CNAME at apex issue” »

I may not get all the terminology correct here, but I’m going to try and explain the issue I’m having. I appreciate any help you’re willing to give! I’m a hobbyist photographer and have owned these two domains for just over a year. My domain host is GoDaddy. I use the “.com” domain as the … Read More “Can’t get forwarding to work on my main domain” »

Transfer DNS service from Cloudflare to Route 53 (no Cloudflare access)

I have limited knowledge of networking so I rely entirely on online guides; sorry if my question appears daft. I have an old, unmaintained website with a faulty database that I can’t access anymore, and a domain name. The hosting and management of the domain was done by a third party that I have no … Read More “Transfer DNS service from Cloudflare to Route 53 (no Cloudflare access)” »

DNS fun…because DNS is always fun! aka probably a stupid question about vpn and local resolution

Hey all, we have Splunk running on a Windows 2016 server, and we need this box to be able to resolve 2 names across a VPN, with all other resolutions going to our normal local Enterprise DNS. Evidently we were using the HOSTS file to accomplish this however the other side of the VPN likes … Read More “DNS fun…because DNS is always fun! aka probably a stupid question about vpn and local resolution” »

Which dns server would I choose?

Main story I bought a router to bypass my ISP router, because of less privacy options… I live in Hungary, and my ISP’s dns server has latency around 770-900 sometimes 1000-1200 ms… It slows my internet a lot down… I tried several public resolvers, but nobody has nodes in Hungary… The nearest ones are in … Read More “Which dns server would I choose?” »

DNSSec and SHA1

Posted on 12/11/2023 By firstdns

Hi Folks,I just wonder what’s your take is on the current DNSSec mess with SHA1. There are still a lot of top level domains being signed with SHA1 and looks like nobody really cares? Current OS releases like RHEL9 and others simply removed SHA1 from the code so if you’re running BIND with “dnssec-validation auto” … Read More “DNSSec and SHA1” »

My isp dns server does not pass the dnssec signature tests. How important is this? According to grc dns benchmark, my isp dns is slightly faster than cloudflare, the second fastest dns server, but cloudflare passes all dnssec signature tests. Would it be wise me to switch to cloudflare or is this really not that … Read More “DNSSEC” »
