Free 1st ip port scanner 2.0 software for windows

Port Scanner 3.0.1 functions as a speedy scanner. A couple of ports have been hard coded to detect what it is but there are others that have not been coded in so it will come up as.

Requirements: Windows 95,98, ME, Windows NT 4.0, W2k Pro, Advance Server, Windows XP home or Pro, Win 32 Bit Systems

Multi-socket scanner capable of scanning local and remote ports quickly, even on slower machines.

DC Port Scanner is, as its name says, a simple and easy-to-use port scanner. DC Port Scanner is, as its name says, a simple and easy-to-use port scanner.
Enter the first three bytes and the trailing dot of an IP address (e.g. "127.0.0."). Click go and a file containing all the open ports will be given.
Must not be used maliciously. Intended as network administrators security analysis tool.
DC Port Scanner is also a small program that does not require any installation.

HighSpeed Port Scanner is a free tool intended for fast search of open ports. Search can be carried out both in a local network, and on the Internet.
Speed of scanning reaches more than 2500 ports per second!
This program doesn?t use the multi-thread algorithm therefore it is not required the big resources in an operating time.
The HighSpeed Port Scanner has three modes of speed of scanning: low, medium and high. Use of each of these modes depends on speed of connection.

NetworkActiv Port Scanner is a network exploration and administration tool that will allow you to scan and explore internal LANs and external WANs. Because of the versatility and choosable operating modes available in NetworkActiv Port Scanner, it may be used by experienced network administrators as well as by novices.
NetworkActiv Port Scanner provides all the basic features that youd expect in an advanced network scanner, but also provides many additional features and technologies, some of which being completely unique to this scanner.
NetworkActiv Port Scanner provides scanning performance simply not found in other Windows based network scanners, but one will need to actually try it to understand just how fast a network scan can be.
Main features:
- TCP connect() port scanner (standard TCP port scanner).
- TCP SYN port scanner (auxiliary TCP port scanner).
- UDP port scanner with automatic speed control.
- UDP subnet port scanner.
- Ping scanning of subnets (UDP or ICMP).
- TCP subnet port scanner, for finding Web servers and other servers.
- High performance trace-route.
- Remote OS detection: Ability to make an educated guess about the OS (Operating System) of a remote host, this is done by TCP/IP stack fingerprinting.
- Wizard Mode: Walks you through step-by-step to perform network scanning, trace-route, and more.
- Whois Client: Ability to perform whois queries, user may either specify a whois server, or have the program attempt to determine a whois server automatically (works with most domains).
- DNS Dig system: Performs DNS dig queries, user may choose between TCP and UDP, specify a DNS server or have the program attempt to determine the authoritative server automatically (works with most domains).
- Simple Port Scanner Mode.
- Graphical user interface, with skin support.
- Ability to notify user if remote computer being scanned is stealth.
- User configurable maximum speed (ranging from 2 PPS to non-limited).
- Attempts to determine host responses for TCP connect() port scanner and subnet port scanner.
- Common port use list, may help user determine the use of an open port.
- Random order, reverse order, and "Only Scan Known Ports" port scanner capable.
- Ability to save the results of the port scanner, subnet port scanner, and other lists to text files.
- Integration between subnet port scanner, port scanner, Windows(c) clipboard, and other programs - customizable.

Many servers and network devices like routers and switches provides features like ACLs, IP Filters, Firewall rules and so on to give access to their Services only to particular network addresses (usually Administrators workstations).
The main purpose of this program is to scan for IP restrictions set for a particular service on a host. It combines "ARP Poisoning" and "Half-Scan" techniques and tries totally spoofed TCP connections to the selected port of the target.
IP Restrictions Scanner was designed not to be a port scanner but a "valid source IP address" scanner for a given service.
