Internet Protocol address, aka IP address, is assigned to a device (modem or wifi router) connected to a network. The standard format of an IPv4 IP address looks something like this, 220.127.116.11
The main purpose of an IP address is to identify the host’s network interface. The IP also provides the location of the host in the network and subsequently the capability of establishing a path to that host.
Besides the two versions of IP addresses, i.e IPv4 (18.104.22.168) and IPv6 (2001:0db8:85a3:0000:0000:8a2e:0370:7334 ), there are also dynamic and static assignments. Dynamic IP’s change while a static IP is fixed and comes at an extra charge from your provider.
Some times your device’s IP may be blocked or blacklisted for various reasons. Please see below explanation of the difference between a blocked and blacklisted IP address:
Blocked vs Blacklisted IP
Following multiple failed login attempts on your e-Mail account, FTP program or admin/host panel, Netmask.host will block your IP for one (1) hour to protect the server against a possible malicious attack. Please note that this temporary block cannot be removed and we request that you access your services through another connection.
Should the issue prevail, while using an alternate connection, you will have to confirm that your password is correct. You can access your webmail in order to check your password and reset it if you are not able to access your account.
If you are not able to access either the client area or host panel with the last known password, kindly make use of the reset password option. If, for some reason you no longer have access to the accounts’ associated e-Mail address, please contact us to assist.
You will be required to provide accurate account details to ensure that you are the primary contact.
a Blacklisted IP address may be related to a virus or malware causing your computer to constantly ping and attempt to communicate with other computers. This might be seen as an ‘attack’, and as a result block your IP address and report it to the relevant institutions. When you send spam or run a mail server that is not properly configured and it allows spam to be sent, that IP address will get blacklisted.
If you have a dynamic (changing) IP address, you’re not a spammer and don’t have a virus, it’s possible that the person(s) who had your IP address before you was and therefore sending of e-Mails will also be affected even if you do not send out spam, high volumes of mails and your e-Mail content is relevant to the subject of the message.
Steps to follow when you suspect that your IP has been blacklisted:
1. If you do not know you IP address, run a Google search by typing “what is my IP”
2. Copy the IP address from the search result, e.g. 22.214.171.124 and Navigate to http://mxtoolbox.com
3. Paste the IP address into the address bar and select “Blacklist Check” from the button’s dropdown.
4. You will now be provided with a list of providers that have possibly blacklisted your IP address.
5. Kindly restart your router to obtain another IP address. Should this prove unsuccessful, kindly contact your ISP and request that they remove the blacklist or alternatively issue a new IP.
Unfortunately it seems that IP’s are simply recycled and not actually removed from the blacklist and therefore it becomes increasingly difficult for normal users who simply make use their internet connection for legitimate browsing and sending of regular business and/or personal e-Mails.
