Good less expensive alternative to some of the competition Overall, I have been satisfied with PDFfiller The software works just like advertised. I love that it is super reliable to work when I need it. The user interface was slightly challenging to get used to but after that, it has been nice.

Easy way to fill in forms online Easy to get things filled in and returned to customers without having to print, write and then scan or fax back. Saves a lot of time in getting payment information from guests. This software doesn't really do anything else except for fill in PDF files. If this is all you need then great but it would be nice if it could do some other tasks with PDF files as well.

PDFFiller I liked being able to create customizable fillable forms for our company. Overall, it is easy to use and responsive. PDF filler is great for a digital signature and saves your previous signature for efficiency. the customizable form feature sometimes lagged and caused minor issues.

Used the product a few times (PDF editor) and really liked it but disn't use it enough to warrant purchase. I forgot to cancel the free trial and was charged the annual fee a few weeks later. The company immediately refunded me when I requested it, and did so without question or issue.

EXCELLENT CUSTOMER SERVICE Very quick, efficient and courteous customer service. My elderly mother subscribed to this service and couldn't remember why. I explained the situation via emails with Customer Support and they refunded the annual subscription fee after I verified a few details. I really appreciated their understanding and quick response. Now...I have to go unplug my mom's computer. :-)

So the longest Internet Header (IP header) size can be 15×32 Bits = 480 Bits = 60 Bytes. This is why the header has a maximum size of 60 Bytes. The shortest header size is 20 bytes, where the ILL field has the value 5 (0101).
As a 4-bit field, the maximum value is 15, this means that the maximum size of the IPv4 header is 15 × 32 bits, or 480 bits = 60 bytes.
The minimum size of an IP packet is 21 bytes (20 bytes for the header, and 1 byte of data). The maximum size is 65,535 bytes.
The Internet Header Length (ILL) field is the number of 32-bit words in the IPv4 header, including any options. Because this is also a 4-bit field, the IPv4 header is limited to a maximum of fifteen 32-bit words or 60 bytes.
With a maximum ILL value of 0xF, the maximum size of the IPv4 header, including options, is 60 bytes (15 × 4).
An Internet Protocol version 4 packet headers (IPv4 packet header) contains application information, including usage and source/destination addresses. IPv4 packet headers contain 20 bytes of data and are normally 32 bits long.
From Wikipedia, the free encyclopedia. An IP header is header information at the beginning of an IP packet which contains information about IP version, source IP address, destination IP address, time-to-live, etc. Two different versions of IP are used in practice today: IPv4 and IPv6.
The minimum length of an IP header is 20 bytes, or five 32-bit increments. The maximum length of an IP header is 24 bytes, or six 32-bit increments. Therefore, the header length field should contain either 5 or 6.
Identification used to differentiate fragmented packets from different data grams. Flags used to control or identify fragments. Fragmented offset used for fragmentation and reassembly if the packet is too large to put in a frame. Time to live limits a data gram's lifetime.
There are 20 bytes in the IP header which leaves 36 bytes for the payload of the IP data gram because we were sending a packet of length 56 bytes.
