Free Reverse Cell Phone Lookup Websites - Do They Exist?

Is it really possible to run a free reverse cell phone lookup on the internet? Many of us have become disillusioned and frustrated in the past with websites which appear to offer free products or services online but in fact do not. Is this the case with cell phone lookups?
Firstly let us examine exactly what we mean by a phone number lookup. If you have in your possession a residential phone number but no idea who the number belongs to or what address it relates to you can use a “reverse lookup” service to find out those details. This can obviously be very useful in situations where you have lost contact with someone but still have a record of their phone number, or simply wish to verify who owns the number before mistakenly phoning the wrong number. There are many places you can perform such residential and business phone lookups online for free, including toll-free numbers.
However a problem arises when you need to run a reverse lookup on a cellular phone as the free directories do not contain any such numbers. Similarly they do not contain fax numbers as this information is only held by the carriers and telecommunications companies. Do these records exist, and are they free?
The good news is there are websites which claim to offer large numbers of cell phone numbers, but they are not free. These websites naturally have to pay for access to some of this information, and go to the considerable trouble of pulling all the various resources together in one place, and as a result you will be charged a small fee before you can access the lookup databases. However the fee is a one-off payment and with some websites you can run as many searches as you like once you have access, with others they offer a single lookup for a lower fee. The records they claim to offer include cell owner details, address history, carrier details, and the phone connection status. It is also worth noting that the databases offered by each company differ to some degree, but most include cell phones and often residential, business, toll-free, even pagers, and these websites say your searches are guaranteed legal and confidential.
In addition to reverse lookups there are also similar websites which offer access to information such as background checks and background reports, people finder databases, bankruptcies, liens, public records databases including births, deaths, marriages, divorces and adoptions, sex offender records, police records, and much more. These sites operate in the same way, offering access to specific types of information for a set fee, however it should be noted that you will not receive access to such information as part of your cell phone lookup site membership.
I have seen websites claiming to offer free cell lookups, but they always lead eventually to the paid sites in the end, even allowing people to search for free and then charging to view the results. It is the sad truth that the only place where you are likely to find detailed reverse cell records is within the legitimate paid directories. In conclusion, the answer is no, free cell phone lookups do not currently exist. However if you really want to access such records then I believe paying a small fee is a price worth paying.

What is a VLAN?

A Virtual Local Area Network (VLAN) is a group of hosts that feature a like set of requirements and can communicate as though they were all connected via the same wires. However, unlike a traditional LAN, a VLAN is not necessarily all in the same place, and the hosts involved in the network can be located practically anywhere. All VLANs have the exact same attributes as a traditional physical local area network, though they can be configured via software instead of having to actually relocate the hosts.
Many VLANs are designed as replacements to the services that are traditionally provided by routers on physical LANs. VLANs are able to tackle issues like network management, security, and scalability with ease.
VLANs are known as Layer 2, or Data Link layer, constructs which transfer data between network nodes. Because they are Layer 2 constructs, they can interface with Layer 3 IP subnets with a one to one relationship.
How are VLANs designed?
The IEEE assigned IEEE 802.1Q as the protocol by which to configure virtual LANs. IEEE 802.1Q provides for a header with a 2-byte protocol identifier and another 2-byte tag control information. These are known as TPID and TCI, respectively. The TPID is fixed at 0×8100 while the TCI contains information pertaining to the user priority, canonical format indicator, and VLAN identifier.
What are the two types of VLAN memberships?
VLAN membership can be assigned in one of two ways. Static or Dynamic.
A Static VLAN is also known as a port based VLAN. These types of VLANs are created by assigning specific ports to a VLAN. As new devices enter into the VLAN network, the device assumes a specific port. If end users change ports but require access to the same VLAN, network administrators are required to assign new port to VLAN assignments for the new port.
A Dynamic VLAN is designed to be easily configured using software. The most common software for designing dynamic VLANs is CiscoWorks, a program developed by Cisco. A VLAN Management Policy Server (VMPS) must be set up first for a dynamic VLAN. This server will allow the VLAN to automatically switch ports whenever new devices connect to the VLAN. It uses information such as the device’s ports, unique usernames, and MAC addresses to determine whether or not to change ports to fit the needs of the incoming device.
