1. Sinfsiz domenlararo marshrutlash (CIDR) tamoyillari

CIDR (RFC 1519) 1993 yilda an'anaviy A, B va C sinflarini almashtirib, o'zgaruvchan uzunlikdagi prefikslarni kiritdi.

Sinfsiz marshrutlash marshrutlarni birlashtirish (supernetting) imkonini beradi va IP manzillar tugashining oldini oladi.

2. Cisco Wildcard maskasini konvertatsiya qilish

Wildcard maskasi quyi tarmoq maskasini bitma-bit teskarilash yo'li bilan hisoblanadi (255.255.255.255 - maska). ACL va OSPF-da keng qo'llaniladi.
