How does ip2long work?
How does ip2long work?
The function ip2long() generates a long integer representation of IPv4 Internet network address from its Internet standard format (dotted string) representation. ip2long() will also work with non-complete IP addresses.
How to check if ip address is in range?
Running ipconfig on a Windows PC
- Click the Start menu.
- In Search/Run bar, type cmd or command, then press Enter.
- In the Command Prompt, type ipconfig or ipconfig/all, then press Enter.

How are the functional groups in IUPAC numbered?
Here all the functional groups such as nitro, alkoxy and chloro groups have no priority and always considered as side chains. So the numbering is given based on the lowest sum of locants and prefixes are arranged in alphabetical order. Here is a video on how to remember the priority order in easy way.
Which is an example of a functional group?
Functional groups are structural units within organic compounds that are defined by specific bonding arrangements between specific atoms. The structure of capsaicin, the compound responsible for the heat in peppers, incorporates several functional groups, labeled in the figure below and explained throughout this section.
How to calculate the priority of functional groups?
Functional groups with equal priority Functional group Formula Prefix Suffix Carboxylic acid COOH Carboxy -oic acid Sulfonic acid SO 3 H Sulfo sulfonic acid Sulfinic acid SO 2 H Sulfino Sulfinic acid Sulfenic acid SOH Sulfeno Sulfenic acid
