DNS: A Quick Summary & FAQ


Humans are better with names than they are with numbers. As such, it's easier to remember the domain name attached to the site (reclaimhosting.com) than the IP address of the server where the site lives (

Because computers are better with numbers, not names, we use a system for translating domains to IP addresses and vice versa. This system is DNS, which stands for Domain Name System. Just as it sounds, DNS is a protocol for names of systems.

DNS Queries


When you type reclaimhosting.com into your web browser, you are asking a resolver, or query participant, to send out a DNS query. A DNS query can look like one of two things:

•A recursive query asks the DNS server, “Can you look for the IP for me and report back?”
•An iterative query says, “if you can’t find it, send along the next place I should look. I’ll keep looking until I find an answer.”

Once the end DNS server receives the query, it sends a message back to your browser which tells your browser which IP address it has located. At that point, the translation is over and the browser communicates using just IP addresses from that point on.

DNS Records

DNS works by holding individual records. Records are simply single mappings between a domain location and a server. You can think of a single record as a single set of directions to follow to find a server, just as if you were trying to find a place in the real world. While there are dozens of record types, some are way more common than others.

A Record: This is your pointer record, which works kind of like speed dial for a host. A Records are the most common DNS records and are used to point a domain/subdomain to an IPv.4 address.

AAAA Record (“Quad-A Record”): This is essentially an updated version of the A record built primarily for the IPv.6 address. So an A record is hardly wrong, but if both the A record and the AAAA record exist, the network will prefer the AAAA record.

CNAME Record ("Canonical Name Record"): This record allows you to refer to a location by more than one name. A CNAME is used to map an alias to a domain name. Ex: mapping the subdomain ‘www.’ to the domain it’s associated with.

MX Record ("Mail Exchange/Mail Exchanger Record"): The MX record is built to identify mail services; it specifies what server is responsible for handling email associated with the domain name. If there are multiple mail servers available, you can prioritize your records.

NS Record ("Nameserver Record"):The NS record helps identify other nameservers in the DNS hierarchy.

TXT Record ("Text Record"): A text record is used to store additional information.

DNS Propagation:

• Changing DNS records will take 24-48 hours to take effect across the Internet.

• Every DNS record has a TTL, or Time To Live. TTL is what dictates how long a DNS record is cached in your local network or browser. WHM’s default TTL setting is 14,400 seconds (4 hours). In the event that a user is migrating off of DoOO or switching to another DoOO server, editing the TTL ahead of time will reduce the time for propagation.

When should I point nameservers and when should I edit my existing A record?

Both essentially accomplish the same task, but there are subtle differences that can make or break your domain– literally. Short answer: You’ll want to edit nameservers when you want the third-party service provider to be in charge of the entire DNS zone for your domain. Meaning, subdomain test.labrumfield.com and email address hello@labrumfield.com would be pointed to the new hosting in addition to the TLD, labrumfield.com. You would change the A record for a domain if you only want that specific domain (or subdomain/subfolder) to be pointed to the new location. So if I edited the A record for project.labrumfield.com to point to Squarespace, I could still use labrumfield.com at Reclaim Hosting.

That said, you can still point all subdomains to a third-party service provider using an A record by creating a Wildcard DNS record. It would look like: *.labrumfield.com pointed at, or whatever the new server IP is. The asterisk basically says point ‘anything’.labrumfield.com to your server.

Couldn’t the user just transfer the domain to the third party service instead of changing nameservers?

Yes, but ICANN requires that the domain is at least 60 days old because a successful transfer is initiated. So if a user wants to begin using their domain elsewhere before the 60-day mark, changing nameservers is a way to make that happen. It can also be helpful to change nameservers before a domain transfer is initiated to minimize downtime.

What are the nameservers for my Domain of One’s Own instance?

All DoOO projects, in addition to Shared Hosting, use the same nameservers: ns1.reclaimhosting.com + ns2.reclaimhosting.com. You can read more information about nameservers here.

My Domain was suspended for failure to verify my email address. I just now verified my email address, but my domain isn’t back online. Why?

When the domain goes into suspension because the user’s email address isn’t verified, our registrar is actually pointing the domain at their nameservers. When the email address is then verified, the registrar points the domain back to our nameservers, causing a DNS delay. We generally tell users that it could take a couple of hours before they see their domain back online, and clearing their browser & network cache can help speed the process along.
