Unix Shell Script to ping systems & make a log

Thanks a Lot !!!
Thanks 'Zaxxon, Spellbound, Mikelking'.. 
Since, I'm new to Unix/Linux Shell-scripting and this forum - kindly bear w/ me, wherever you find me a (dumb) rookie!
________________________________________________________
My overall aim is :
1. To ping my office-network..
2a. Create a log for successful pings and unsuccessful ones..
>> till here - i'm done<<
2b. Create a DNS kinda thingy..
>> done - but, i'm using 'if-else' here (..plz don't laugh..) <<
>> my boss said, rather than 'if-else', use a file - where <<
>> from you import all the names for particular IPs.. <<
3. Generate/create a Network-Outage report, that gives the timestamps for
whenever the ping was unsuccessful for that particular IP (as rightly mentioned by 'Zaxxon')..
4. Question arises - what's the need for successful IPs..!?
Answer - I need to run network-related commands on those successful IPs,
to generate another log that gives me all the system-related-info (such as Memory/Disk-usage, N/W-usage, blah! blah! blah!) of/for those particular (successful) IPs..
[in short - have to make my own NMS (n/w mgmt. sys.) for my company ]
________________________________________________________
My problem :
1. I'm not good at googling.. :'(
2. I've a few commands, like :
vmstat, netstat, nslookup, traceroute, ifconfig, df, du, iostat, iptables, chkconfig, etc.
but these work for my system (not all f 'em) and i need to sit on my system
and use the above commands (or, similar) on all the systems on the n/w via. IPs..
3. As of now, the bit I'm struggling w/ is:
using 'grep' to fetch the IP from the same line where I'm grepping - "unreachable host"..

mfontset_lookup
mfontset_lookup(3m17n) The m17n Library mfontset_lookup(3m17n) NAME
mfontset_lookup - Lookup a fontset. SYNOPSIS
MPlist * mfontset_lookup (MFontset * fontset, MSymbol script, MSymbol language, MSymbol charset) DESCRIPTION
Lookup a fontset. The mfontset_lookup() function lookups fontset and returns a plist that describes the contents of fontset corresponding to the specified script, language, and charset. If script is Mt, keys of the returned plist are script name symbols for which some fonts are specified and values are NULL. If script is a script name symbol, the returned plist is decided by language. o If language is Mt, keys of the plist are language name symbols for which some fonts are specified and values are NULL. A key may be Mt which means some fallback fonts are specified for the script. o If language is a language name symbol, the plist is a FONT-GROUP for the specified script and language. FONT-GROUP is a plist whose keys are FLT (FontLayoutTable) name symbols (Mt if no FLT is associated with the font) and values are pointers to MFont. o If language is Mnil, the plist is fallback FONT-GROUP for the script. If script is Mnil, the returned plist is decided as below. o If charset is Mt, keys of the returned plist are charset name symbols for which some fonts are specified and values are NULL. o If charset is a charset name symbol, the plist is a FONT-GROUP for the charset. o If charset is Mnil, the plist is a fallback FONT-GROUP. RETURN VALUE
It returns a plist describing the contents of a fontset. The plist should be freed by m17n_object_unref(). COPYRIGHT
