Easiest way. Take the integer, plug it into windows 'calc'. Go to 'View: Scientific'. Hit 'Hex'. That will show you the hex representation of the integer. Notice that it's either 7 or 8 characters long. If it's 7, prepend it with a 0. Break that into 4 groups of 2. Those are the hex values for the four dotted quads. Make sure 'Hex' is still selected, and put in the first 2 characters, then hit 'binary'. That's your first part of the IP. Repeat for the other 3. For example, you have 1089055123 for an integer. In Hex thats 40E9A993. 40 Hex = 64 E9 Hex = 233 A9 Hex = 169 94 Hex = 147 So your IP is 64.233.169.147 Ken ________________________________ From: Colin Alston [mailto:karnaugh@karnaugh.za.net] Sent: Wed 8/27/2008 5:21 AM To: kcc Cc: nanog@nanog.org Subject: Re: interger to I P address kcc wrote:

OK... I'll bite... The pedantic way: No. IP addresses are already integers. All conversation on this topic has been about how to convert between different methods of representing integers, but, at the end of the day, IP addresses are either 32 (IPv4) or 128 (IPv6) bit integers. There is no conversion possible or required between IP addresses and integers as the set of {IP Addresses} is a true subset of the set {integers}.

For the curious, have a look at the IASON tools http://iason.site.voila.fr/ and try c:~$ natnum 1089055123 host_look("64.233.169.147","1089055123","1089055123"). host_name("64.233.169.147","yo-in-f147.google.com"). natnum takes a hostname, an integer or an IPv4 address and shows you the IPv4 address, the integer and the hostname. If you do maintain your /etc/hosts it will tell you the aliases too. Most of the stuff is unix only, but I guess you can compile natnum even for windows. Kind regards Peter Matlock, Kenneth L wrote:

If you are using 128-bit integers, which according to some will also change some day, thus one should be using "struct addrinfo" and: getaddrinfo() getnameinfo() as those are the girlfriends of programmers. Note that one should effectively avoid inet_pton/inet_ntop as they still require the programmer to know about address families, the get*info() ones ignore all those details.

Perl provides some cleaner methods for interpreting/displaying IPs. There isn't a formal standard notation for an IP that looks like a string of decimal digits with no dots though. I.e. no RFC will define the host byte order and tell you that "127.0.0.1" corresponds to the decimal integer 2130706433; I might be little-endian and argue that the right human-readable integer to call that ip is 16777343. There are a vast number of different numerical representations the very same ip address could be converted to, because a string of bits has no inherent representation. Displaying an IP in a novel format seems dangerous. Ips have only a binary notation and.. in recent years dots-and-decimals are formalized. In general, rather than just in the context of SMTP. Still conflicting conventions exists that haven't been fixed, for example try pinging "127.1" (hint: it's an old abbreviation mechanism not merely a "bug") In any case, to get from quad-octet notation to a decimal integer representation you may be thinking of (if you interpret those octets in the network byte order used for other items such as port numbers): $ perl -e 'use IO::Socket; print unpack("N",inet_aton("127.0.0.1"))."\n"' 2130706433 $ perl -e 'use IO::Socket; print inet_ntoa(pack("N",2130706433))."\n";' 127.0.0.1 $ perl -e 'use IO::Socket; print inet_ntoa(pack("N",2066563929))."\n";' 123.45.67.89 And of course... $ perl -e 'print "",(123<<24)|(45<<16)|(89<<8),"\n"' 2066569472 Or if you don't like one-liners, 3 separate short scripts: ipv4-to-hex: #!/usr/bin/perl use IO::Socket; printf("%x\n", unpack("N",inet_aton($ARGV[0]))); ipv4-to-integer: #!/usr/bin/perl use IO::Socket; printf("%d\n", unpack("N",inet_aton($ARGV[0]))); hex-to-ipv4: #!/usr/bin/perl use IO::Socket; print inet_ntoa(pack("N",hex($ARGV[0]))); On Wed, Aug 27, 2008 at 9:13 AM, Michael Holstein <michael.holstein@csuohio.edu> wrote:

Thank you
My two cents: # ping 1089055123 PING 1089055123 (64.233.169.147) 56(84) bytes of data. 64 bytes from 64.233.169.147: icmp_seq=1 ttl=248 time=2.55 ms 64 bytes from 64.233.169.147: icmp_seq=2 ttl=248 time=2.00 ms To do in reverse, you can use 'sipcalc': # sipcalc 64.233.169.147 -[ipv4 : 64.233.169.147] - 0 [CIDR] Host address - 64.233.169.147 Host address (decimal) - 1089055123 Host address (hex) - 40E9A993 Network address - 64.233.169.147 Network mask - 255.255.255.255 Network mask (bits) - 32 Network mask (hex) - FFFFFFFF Broadcast address - 64.233.169.147 Cisco wildcard - 0.0.0.0 Addresses in network - 1 Network range - 64.233.169.147 - 64.233.169.147 -evt
Ruby's IPAddr class is quite handy for IPv4 and IPv6 integer representation conversions. For IP to integer, whether IPv4 or IPv6, ruby code: require 'ipaddr' print "#{IPAddr.new('10.0.0.55').to_i}\n" print "#{IPAddr.new('2001:0db8:85a3:08d3:1319:8a2e:0370:7334').to_i}\n" Results in: 167772215 42540766452641195744311209248773141300 And for integer to IPv4, ruby code: require "ipaddr" print "#{IPAddr.new(167772215,Socket::AF_INET)}\n" Results in: 10.0.0.55 And for integer to IPv6, ruby code: require 'ipaddr' print "#{IPAddr.new(42540766452641195744311209248773141300, Socket::AF_INET6)}\n" Results in: 2001:0db8:85a3:08d3:1319:8a2e:0370:7334 Aaron out.
Howdy, Careful, this appears to not be inline with another persons thoughts. Not mine mind you. "Anything concerning an "end network" is not relevant to this list. " lol I am however, very interested in the content/replies thus far. Very entertaining. Ok, sorry, back to the scheduled programs. -Joe

sure. how do you want that IP? hex? octal, decimal, binary? (*) v4 or v6?
* other bases by request....

Yes, while certainly off topic, also for me it's probably been one of the most entertaining threads of this kind. So just one more solution, as there's so much unused processing power available on all your PostScript gear: Let your printer do the math! ##### BEGIN of ntoa.ps ##### %! /ntoa { 3 { dup 256 idiv exch 256 mod exch } repeat 256 mod } def /printa { 3 string cvs show 3 { (.) show 3 string cvs show } repeat } def /Helvetica findfont 36 scalefont setfont 36 444 moveto 1089055123 ntoa printa showpage ###### END of ntoa.ps ######
