Web Development

Since you mention using Godaddy, have you requested help from them on what could be happening?

This is what I have found from Godaddy's documentation:

ADD AN A RECORD

An A (host) record connects your domain name to your IP address. A records let users enter your domain name in a Web browser to access your website. They are the most common type of zone record.

Follow the directions to access the DNS Manager.

Click Add Record.

From the Record type list, select A (Host).

Complete the following fields: Host Name — Enter the host name the A record links to. Type @ to point the record directly to your domain name, including the www.

Points to IP Address — Enter the IP address your domain name uses for this host record.

TTL — Select how long the server should cache the information. Click OK, then click Save Zone File. The new A record displays in the A (Host) section.

ADD A CNAME RECORD

A CNAME (Alias) record points to an A (Host) record. You can create multiple CNAME records and point them to an A record. The most common CNAME records are the subdomains www and ftp.

CNAME records make your DNS data easier to manage. If you change the IP address of an A record, all CNAME records pointed to that A record automatically follow the new IP address. The alternative solution, multiple A records, is not as simple as using CNAME records.

Follow the directions to access the DNS Manager.

Click Add Record.

From the Record type list, select CNAME (Alias).

Complete the following fields: Enter an Alias Name — Enter the subdomain name for the alias assignment. For example, type www. Points to Host Name — Enter the host name you want the alias to point to. For example, type @ to map the alias directly to your domain name.

TTL — Select how long the server should cache the information.

Click OK, then click Save Zone File.

You can click Restore Defaults in the CNAME (Alias) section of the Zone File Editor to restore the default CNAME records for your domain name.

from outside your network (home) or connected via another connection
Go to the command prompt and type NSlookup server.domain.com (where this equals your server name). see what address it returns if that IP address is incorrect you probably need to check your external DNS entry.
Additionally you can type
NSLOOKUP
Server 8.8.8.8
server.domain.com (where this equals your system name).
something like
*** google-public-dns-a.google.com can't find nothing.ext: Non-existent domain
would mean whoever is hosting your external DNS is not pushing out your DNS entries. Note: even after it's fixed it may take a while to replicate a round (up to 48 hours)

Reserved address ranges, accessed from the outside world by NAT (your internal network address translation server)
10.0.0.0 to 10.255.255.255 Class A
172.16.0.0 to 172.31.255.255 Class B
192.168.0.0 to 192.168.255.255 Class C
127.x.x.x Loop back referring to the current host. Meaningless to the outside.
If your web server's address is in any of the reserved ranges, it'll need to have a fixed ip address and you'll have to configure NAT to know how to get to it. Also, it will share the same gateway and subnet mask as other hosts on its subnet. If the web server is using one of your addresses provided by your IP provider, then it will need the same gateway and subnet mask as the one that's outward facing on the router that's attached to the internet.

Got it! Thank you guys I ended up having a complete noob mistake and forgot to put my domain in the "www" slot!
