IPv6: Bermain Dengan ipv6calc
ipv6calc adalah sebuah utility kecil yang di tulis menggunakan bahasa C untuk memanipulasi IPv6 address maupun berbagai trick lainya. Keterangan lebih lanjut dari ipv6calc bisa di baca di http://www.deepspace6.net/projects/ipv6calc.html
Instalasi ipv6calc dapat dilakukan menggunakan perintah
# sudo apt-get install ipv6calc
Melihat kemampuan built in ipv6calc
# ipv6calc -vvv
akan keluar kira-kira

Contoh paling sederhana adalah konversi IPv6 address ke DNS PTR query string:
$ ipv6calc --out revnibbles.arpa 2001:db8::1
Hasilnya
No input type specified, try autodetection...found type: ipv6addr 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa.
Seperti yang kita lihat, format input auto detect. Ipv6calc juga mengerti tentang masking / nilai panjang prefix
$ ipv6calc -q --out revnibbles.arpa 2001:db8::1/64
Hasilnya
0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa.
Kita juga belajar bawa switch '-q' (quiet) akan menghilangkan message yang sifatnya informasi. Ipv6calc dapat kita gunakan untuk melakukan query DNS PTR, contoh
$ dig PTR `ipv6calc -q --out revnibbles.arpa 2001:db8::1/64`
Akan keluar:
; <<>> DiG 9.9.5-3-Ubuntu <<>> PTR 0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa. ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 38359 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa.

Tentunya ipv6calc dapat melakukan lebih banyak hal untuk kita. Contoh berikut adalah mengekstrak IPv4 address yang berada dalam 6to4 IPv6 address:
$ ipv6calc -q --action conv6to4 --in ipv6 2002:c0a8:fb61::1 --out ipv4
Hasilnya
192.168.251.97
Atau sebaliknya, kita ingin mengkonversikan IPv4 ke format IPv6.
$ ipv6calc -q --action conv6to4 --in ipv4 192.168.251.97 --out ipv6
Hasilnya
2002:c0a8:fb61::
Kita juga dapat memperoleh informasi tentang sebuah IPv6 yang sederhana:
$ ipv6calc -q -i 2404:6800:4001:c01::67
Hasilnya
Address type: unicast, global-unicast, productive, iid, iid-local Address type has SLA: 0c01 Registry for address: APNIC Country Code: AU Interface identifier: 0000:0000:0000:0067 Interface identifier is probably manual set GeoIP country name and code: Australia (AU)
Contoh lain
$ ipv6calc -q -i 2404:6800:4001:c01::67
Hasilnya
Address type: unicast, global-unicast, productive, iid, iid-local Address type has SLA: 0c01 Registry for address: APNIC Country Code: AU Interface identifier: 0000:0000:0000:0067 Interface identifier is probably manual set GeoIP country name and code: Australia (AU)
Contoh Lain
$ ipv6calc -q -i 3ffe:ffff::210:a4ff:fe01:2345
Hasilnya
Address type: unicast, 6bone, global-unicast, iid, iid-global, iid-eui48 Address type has SLA: 0000 Registry for address: IANA Error getting country code for IPv6 address Interface identifier: 0210:a4ff:fe01:2345 EUI-48/MAC address: 00:10:a4:01:23:45 MAC is a global unique one MAC is an unicast one OUI is: XIRCOM
Informasi tentang sebuah Teredo IPv6 address:
$ ipv6calc -q -i 3ffe:831f:ce49:7601:8000:efff:af4a:86BF
Hasilnya
Address type: unicast, 6bone, global-unicast, teredo IPv4 address: 80.181.121.64 IPv4 address type: unicast, global Country Code: IT IPv4 registry[80.181.121.64]: RIPENCC GeoIP country name and code: Italy (IT) IPv4 address: 206.73.118.1 IPv4 address type: unicast, global Country Code: US IPv4 registry[206.73.118.1]: ARIN GeoIP country name and code: United States (US) Address type is Teredo and included IPv4 server address is: 206.73.118.1 and client port: 4096 IPv4 registry for Teredo server address: ARIN Registry for address: IANA Error getting country code for IPv6 address
Memang ada mechine readable output (seperti 'ipv6calcweb.cgi') – sebagai tambahan, berikut adalah IP2Location dan atau GeoIP information yang dapat di tampilkan jika database di berikan.
$ ipv6calc -q -i -m 2001:470:36:ab6:203:dff:fee3:db76
