You may have heard about IPv6 and wondered what on earth it is and what it will mean for you when this new Internet Protocol is introduced. This article should help to answer those questions:
What is IPv6?
Every device that connects to the Internet is given a unique number known as an IP address. The current model, IPv4, has approximately 4 billion of these unique addresses however with the boom in Internet enabled devices (tablets, phones, TVs, fridges etc) there are very few IPv4 addresses remaining. In other words, the Internet is running out of space! The new model, IPv6, can handle 340 undecillion addresses (that’s 340 trillion trillion trillion or 340,000,000,000,000,000,000,000,000,000,000,000,000) which gives the Internet a _lot_ more room to grow.
The expansion is made possible by the different structure of an IPv6 address, however networks and devices need to be updated in order to understand and communicate with them. Below is an example of how each IP address appears:
IPv4 188.8.131.52 (32 bits long)
IPv6 2001:db8::1234:ace:6006:1e (128 bits long)
What will IPv6 mean to me?
If you don’t deal with Information Technology then you will happily have very little to do with the move to IPv6. It is up to us (and your other IT support providers) to manage the transition from IPv4 to IPv6 without affecting your use of Internet applications.
The transition has already begun and we provide native IPv6 for our colocation and VPS customers* over one of our fibre pathways and IPv6 via tunnelling for an alternate pathway. For our web hosting customers we have begun testing our web server cluster in a ‘dual-stack’ configuration, meaning it will be able to respond to requests over IPv4 and IPv6. We will provide updates on our Twitter feed when this feature has been fully tested and activated.
Once all global networks have completed the switch IPv4 will no longer be required and will be phased out, although this may take a few decades. If you would like to test your IPv6 connectivity please visit http://test-ipv6.com.
*If you are a colocation or VPS customer and would like to enable your IPv6 address please contact us.
Many customers have difficulty choosing between IMAP and POP mail protocols when setting up their email accounts, and for good reason – it can be confusing!
POP (Post Office Protocol) is the traditional method used by email programs to retrieve e-mail from a mail server. The important feature of POP is that when you retrieve your email the messages are moved from HostAway’s server to the computer/device you are using. Emails can be kept on the mail server for a number of days before being deleted (this is determined by the advanced settings in your mail program), allowing you to download the messages onto multiple devices before they are purged. POP accounts have a one way communication with our mail server simply pushing a copy of all mail out to each connecting device, leaving each device with its own copy of the emails which must be organised individually. They run fairly autonomously and do not encounter quota issues unless receiving large amounts of mail with attachments or if they are not set to purge old emails frequently enough.
The advantages of POP are:
- Message storage limited only by the capacity of your computer.
- Little remote storage required (if you have the default setting to delete emails from the server once they are delivered to your device).
The disadvantages of POP are:
- Reading your e-mail from multiple computers or e-mail programs results in duplication of filing and deleting emails.
- Messages are stored locally on your computer. If your computer fails you may lose all your email.
IMAP (Internet Message Access Protocol) is the other major method used by email programs to retrieve mail. Unlike POP, IMAP keeps your messages on the server, therefore when you click to read an email IMAP presents the message that is stored on the server. IMAP accounts are a two way communication with our mail server where each device talks to our mail server to organise and view mail. All devices will see the same messages and an email that is moved to a folder on one device will be moved on all devices. As an IMAP account leaves all messages on our mail server they require some end user diligence to monitor quota usage.
The advantages of IMAP are:
- Messages are stored on the server and are not affected if your computer fails.
- Easily use multiple computers or e-mail programs to read mail.
The disadvantages of IMAP are:
- Message storage is limited (this is dependent on your hosting plan and mailbox quota allocation)
- Reading messages while offline requires use of your e-mail program’s Offline mode.
If you plan to view your mailbox from multiple devices (computer, laptop, smartphone) and plan to manage your mailbox size then we recommend using IMAP. If you are simply using one mail program or device (such as Outlook on your Windows PC or Mac Mail on your Apple PC) or don’t want to worry about mailbox quota then we recommend POP.
For help configuring your mail clients to either POP or IMAP simply give us a call on 9249 3646. Or you can view our tutorials at https://www.hostaway.net.au/support/email/
- It is possible to change your email account from POP to IMAP and vice versa, however this is a setting on your mail program (Outlook or Mac Mail for example) and not on the server.
- All mailboxes are 100MB in size by default. You can allocate more quota to individual mailboxes using the Email Quota Manager in the HostAway Members Panel and if required you can purchase more assignable quota. Please be aware that unless you purge or archive older emails your IMAP account will continue to grow in size over time.
- When you send email from some devices it may not save the sent message to your IMAP account by default (eg. An iPhone saves this locally by default). You may need to edit your settings to save sent messages to an IMAP folder if you wish for this to be saved within your IMAP account.
- If you use Webmail you are effectively using IMAP. If you have a POP account and want to use Webmail whilst on holiday make sure you don’t leave your mail program open on your home/office PC or it may download all of your recent emails.
- Both POP and IMAP accounts will work being used across multiple devices including desktops, laptops, mobile phones and any other email capable device you can think of however the support does vary between account types.
- SMTP (Simple Mail Transfer Protocol) refers to outgoing mail, not incoming – both POP and IMAP accounts use SMTP when sending emails. You have a choice of using your ISP’s outgoing mail server or HostAway’s.
This scam has been around for a few years however a number of customers have reported a resurgence of this unsolicited email. An example of this scam is:
We are a Network Service Company which is the domain name registration center in Anhui, China. On May,7th,2012, We received HUHUA Company’s application that they are registering the name “YOUR COMPANY NAME” as their Internet Trademark and “YOURCOMPANYNAME.cn”, “YOURCOMPANYNAME.com.cn”, “YOURCOMPANYNAME.asia” domain names etc. It is China and ASIA domain names. But after auditing we found the brand name been used by your company. As the domain name registrar in China, it is our duty to notice you, so I am sending you this Email to check. According to the principle in China,your company is the owner of the trademark. In our auditing time we can keep the domain names safe for you firstly, but our audit period is limited, if you object the third party application these domain names and need to protect the brand in china and Asia by yourself, please let the responsible officer contact us as soon as possible. Thank you!

These emails may contain different wording and formatting, however they generally follow these rules:
- They claim to have received an application by another company who want a .cn domain name that uses your company name or trademark.
- They claim to be authorised by the CNNIC (China Internet Network Information Center) which is the Chinese Domain Registry.
- Their grammar and spelling is often atrocious.
- They claim they want to help you to stop the other company from registering the .cn domain name in question.
- The emails often have full contact details including phone, email and fax, making them seem more legitimate.
- Prices are seldom mentioned (and can be many times more expensive than the going rate).
- The reply addresses that these emails appear to come from vary, sometimes coming from .cn addresses and sometimes from Gmail, Hotmail, Yahoo etc addresses.
If you receive one of one of these emails don’t reply. Simply delete the email or if you are unsure please contact us.
If you want to register a .cn domain name send us an email and we can check the availability.
You are probably familiar with some of the many Phishing attempts circulating the Internet (whereby someone fraudulently tries to acquire your information by pretending to be a trustworthy organisation) however there are a few ‘companies’ that have been mailing out letters for domain name renewals with something that appears to be an invoice.
These letters originate from companies such as Domain Register, Domain Name Group or Domain Renewal Group however they often change their names so please read your letter carefully. They apparently avoid breaking the law by including a small note claiming ‘this is not an invoice’ or ‘this is an invitation to register’. They will also sometimes offer a free iPod or prize but be warned, if they manage to gain control of your domain name you will be hit with very high renewal fees and hosting costs.
If you are in doubt please give us a call – we can quickly advise whether the invoice is legitimate or not! For more information we recommend you visit The Scamwatch Website
You can now edit your mailbox quota through the HostAway Members Panel. Each new mailbox is 100MB in size by default, however with this new tool you can now resize your mailboxes and take advantage of all the space you are entitled to. To access simply select ‘Email Quota Manager’ on the left hand menu within the Members Panel. If you require additional space this can be added in blocks which can be shared across all your mailboxes or allocated to a single large mailbox.
You can now add “subdirectory subdomains” to your website through the HostAway Members Panel with the click of a button. For those of you who aren’t familiar with the term, a subdomain is an extra level to your domain name, allowing you to divide your website into different sections without registering a new domain name, eg. help.hostaway.net.au.
This new self management feature links a folder within the ‘htdocs’ directory of your domain, so that your existing website quota is used for the subdomain. You may recognise this type of subdomain from similar tools like cPanel. We still offer our “classic subdomains” as a separate product, for those subdomains you want to isolate from other sections of your website (in terms of web space, user account and FTP access). If you have any questions about this feature or would like to change your classic subdomains to the new method please contact us.
