DNS/Hosting

DNS:

Short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. webopedia.com

Web Server:

A computer that delivers Web pages to browsers and other files to applications via the HTTP protocol. It includes the hardware, operating system, Web server software, TCP/IP protocols and site content (Web pages and other files). If the Web server is used internally and not by the public, it may be called an "intranet server." pcmag.com

A Record:

An entry in your DNS table (zone file) that maps each domain name (e.g. you.com) or subdomain (e.g. abc.you.com) to an IP Address. In other words, the A record specifies the IP address to which the user would be sent for each domain name. For example, you can have abc.you.com point to one IP address, and xyz.you.com point to a different IP address. free-webhosts.com

MX Record:

Short for mail exchange record, an entry in a domain name database that identifies the mail server that is responsible for handling e-mails for that domain name. webopedia.com

CNAME Record:

The Canonical Name (CNAME) record is used to create aliases that point to other names. It is commonly used to map WWW, FTP and MAIL subdomains to a domain name; for example, a CNAME record can associate the subdomain FTP.COMPUTERLANGUAGE.COM with COMPUTERLANGUAGE.COM. pcmag.com

DNS Name Servers Record:

DNS Name Servers (NS) The Name Server (NS) record identifies the authoritative DNS servers for a domain. A second name server is required for redundancy, and two NS records must be in the zone file (one for the primary; one for the secondary). The secondary server queries the primary server for changes. pcmag.com

Domain Names

Domain Name Privacy:

This type of anonymous domain registration is only available on .COM and .NET domain names.

ICANN:

The Internet Corporation for Assigned Names and Numbers (ICANN) is an internationally organized, non-profit corporation that has responsibility for Internet Protocol (IP) address space allocation, protocol identifier assignment, generic (gTLD) and country code (ccTLD) Top-Level Domain name system management, and root server system management functions. These services were originally performed under U.S. Government contract by the Internet Assigned Numbers Authority (IANA) and other entities. ICANN now performs the IANA function.

ICANN is responsible for coordinating the management of the technical elements of the DNS to ensure universal resolvability so that all users of the Internet can find all valid addresses. It does this by overseeing the distribution of unique technical identifiers used in the Internet's operations, and delegation of Top-Level Domain names (such as .com, .info, etc.). Other issues of concern to Internet users, such as the rules for financial transactions, Internet content control, unsolicited commercial email (spam), and data protection are outside the range of ICANN's mission of technical coordination.

As a private-public partnership, ICANN is dedicated to preserving the operational stability of the Internet; to promoting competition; to achieving broad representation of global Internet communities; and to developing policy appropriate to its mission through bottom-up, consensus-based processes.

Life Cycle:

Day 7 - If auto-renew is off - NS changed to Expired Monetization

Day 15 - If auto-renew is on, non-paid - NS changed to Expired Monetization

Day 35 - If domain is in APRO Rodopi - Domain deletion End of Registrar Grace Period. Beginning of redemption period.

Day 40 - If domain is in N4E Rodopi - Domain deletion End of Registrar Grace Period. Beginning of redemption period.

Day 65 - If domain is kept for monetization - Redemption period ends. Original registrant is no longer able to redeem the domain.

E-mail

Account type - IMAP:

1. Account name (Username): your entire email address, including @yourdomain.com.

2. Password: the password that you set when you created your e-mail box in your Aplus.Net Control Panel

3. Incoming Mail Server: mail.yourdomain.com (Please, replace yourdomain.com with your hosted domain name).

4. Incoming Server Port and Connections settings – Port 993 with secure connection over SSL.

5. Outgoing Mail Server: smtp.yourdomain.com (Please, replace yourdomain.com with your hosted domain name)

1. Authentication –Turn on Outgoing Server Authentication and use the username and password as specified in 2 and 3.

2. SMTP Port and Connection settings - you have two options:

Outgoing (SMTP) mail port: 465. You have to use SSL secured connection for the Outgoing mail server.

Outgoing (SMTP) mail port: 587. You have to use TLS secured connection for the Outgoing mail server.

Because you have configured your email client to receive messages over a secure connection (step5), it is possible that your email client displays a warning message concerning the Secure Certificate installed on the mail server. In order to avoid this warning message, you can replace the incoming mail server (mail.yourdomain.com) with the email server name.

Account type - POP3:

1. Account name (Username): your entire email address, including @yourdomain.com.

2. Password: the password that you set when you created your e-mail box in your Aplus.Net Control Panel.

3. Incoming Mail Server: mail.yourdomain.com (Please, replace yourdomain.com with your hosted domain name).

4. Incoming Server Port and Connections settings –you have the following options:

Port 110 with regular connection (without SSL).

Port 110 with secure connection over TLS.

Port 995 with secure connection over SSL.

5. Outgoing Mail Server: smtp.yourdomain.com (Please, replace yourdomain.com with your hosted domain name).

1. Authentication –Turn on Outgoing Server Authentication and use the username and password as specified in 2 and 3.

2. SMTP Port and Connection settings - you have two options:

Outgoing (SMTP) mail port: 465. You have to use SSL secured connection for the Outgoing mail server.

Outgoing (SMTP) mail port: 587. You have to use TLS secured connection for the Outgoing mail server.

Spam Cannibal

We have received some information back from spamcannibal regarding who and what they block. Basically what the below message states is that they only block access to their own server's but that other networks can use their list on their server's. This makes it tricky because technically they are not responsible for any server's using their list and as such they normally do not remove ip's that are blocked lightly. The following is the message we received.

Spamcannibal does not block ANY mail except at its own site. Access to our mail servers is restricted for hosts and dynamic/un-named netblocks that have previously sent UBE/UCE to our mail system. If a third party has reported that they are blocking your mail you should contact them directly for whitelisting. Our database is public and may be inspected by anyone so that they can see why specific hosts not allowed to send messages to our mail system. Perhaps some third party is using this information for their own purposes. You are in a spammy netblock and your IP address has a PTR record that fits the regular expression used by many mail systems (including ours) to reject mail from unnamed, generic, and dynamic sources. Your IP address appears to be part of such a dynamic/generic/un- named class C. Since over 75% of all spam comes from such sources, rejection based on this criteria is not likely to ever change.

Each mail host must have a unique non-script generated PTR record. If you wish to send email from a host, then you should either use your ISP's smart host or contact your ISP and have a distinguishing PTR record entered for your static IP address. A PTR record for 11.22.33.44 of 11-22-33-44.some.provider.com or a similar alphanumeric script generated reverse entry do not qualify for removal. Either route your outbound mail through your ISP's smart host or let us know when your mail host has been provisioned with a distinguishing PTR record.

SQL

SQL:

Abbreviation of structured query language, and pronounced either see-kwell or as separate letters. SQL is a standardized query language for requesting information from a database. The original version called SEQUEL (structured English query language) was designed by an IBM research center in 1974 and 1975. SQL was first introduced as a commercial database system in 1979 by Oracle Corporation. webopedia.com
