: No to może tak:
: 3279200769/(256^3) = 195
: 3279200769-195*256^3 = 7643649
: 7643649/(256^2) = 116
: 7643649-116*256^2 = 41473
: 41473/256 = 162
: 41473-162*256 = 1
: 195.116.162.1
: bort@zeus:~ $ nslookup 195.116.162.1
: Name Server: zeus.polsl.gliwice.pl
: Address: 157.158.1.3
: Name: gryzmak.lodz.pdi.net
: Address: 195.116.162.1
Autopoprawka - żeby jeszcze wyeliminować użycie nslookup, należało to
zrobić tak:
perl -MSocket -e 'printf("%s %s\n", Socket::inet_ntoa(pack("N",3279200769)),
gethostbyaddr(pack("N",3279200769),AF_INET))'
Coraz bardziej się przekonuję do Perla...
