The whole domain name can not exceed a total length of 255 characters, but some registries have shorter limits.
Domain Registrar
Domain registrars sell Internet domain if your domain registrar is separate from your domain host, you'll need to add the host's name servers to your registrar's account.
(which offers domain registration) and host your domain with DynDNS (which offers domain hosting), you'll add the name servers of DynDNS (ns1.mydyndns.org and ns2.mydyndns.org) to your account with namecheap.com.
Google Apps for Your Domain offers domain registration with a select group of domain registration partners. This allows you to purchase a domain name and sign up for Google Apps at the same time. If you purchase a domain name while signing up, Google will auto-configure services for your domain so that you won't need to manually configure MX and CNAME records.If you purchased your domain name before signing up for Google Apps, visit our list of domain hosts that have instructions for modifying MX records..
Domain Host
Domain hosts run DNS servers for your domain. This includes A records, MX records, and CNAME records. Most domain hosts offer domain name registration as well Since Google Apps for Your Domain is not a domain host, you'll need to modify your DNS records with your domain host to set up email and web publishing. Click here if you don't know which company is hosting your domain.
A Record
A records (also known as host records) are the central records of DNS. These records link a domain, or subdomain, to an IP address A records and IP addresses do not necessarily match on a one-to-one basis. Many A records correspond to a single IP address, where one machine can serve many web sites. Alternatively, a single A record may correspond to many IP addresses. This can facilitate fault tolerance and load distribution, and allows a site to move its physical location.
Google Apps for Your Domain does not support IP addresses alone. Instead of using A records, you can set up email and web publishing by modifying your MX and CNAME records with your domain host.
NS Record
Name server records determine which servers will communicate DNS information for a domain. Two NS records must be defined for each domain. Generally, you will have a primary and a secondary name server record - NS records are updated with your domain registrar and will take 24-72 hours to take effect.
If your domain registar is separate from your domain host, your host will provide two name servers that you can use to update your NS records with your registrar.If you're not sure who is hosting your domain, you can perform a free NS Lookup. Here's how:
